Nursing Fundamentals Midterm Review

In the event of a narcotic count discrepancy, it is crucial to prioritize patient safety and adhere to legal and facility protocols. Reporting the discrepancy to the charge nurse ensures that the issue is addressed promptly and allows for an investigation to prevent potential medication errors or misuse. Following established protocols is essential for maintaining accountability and compliance with regulations surrounding controlled substances. Ignoring the discrepancy or attempting to resolve it independently could lead to serious consequences for both patient care and the nurse's professional responsibilities.

To prevent falls in at-risk patients, ensuring that the call light is within reach empowers them to request assistance when needed, promoting safety. Keeping the bed in the lowest position minimizes the risk of injury if the patient attempts to get out of bed. This approach focuses on patient autonomy and safety, rather than restricting movement with restraints or sedatives, which can increase the risk of falls and compromise patient well-being. Thus, the priority is to enable safe access to help while maintaining a low risk environment.

The Z-track technique involves displacing the skin and subcutaneous tissue laterally before inserting the needle for an intramuscular injection. This method helps to create a zigzag path that seals the medication in the muscle, preventing it from leaking into the subcutaneous tissue, which can cause irritation or discomfort. After injecting, the skin is released, allowing it to return to its original position, further ensuring that the medication remains in the muscle. This technique is particularly useful for administering irritating medications.

Objective data refers to measurable and observable information that can be verified by others. In this case, the blood pressure reading of 148/92 mmHg is quantifiable and can be consistently assessed using medical equipment, making it an objective measure of the patient's health. In contrast, the other options are subjective, relying on the patient's personal experiences or feelings, which can vary from person to person and cannot be independently verified.

Decreased skin turgor is a clinical sign that indicates reduced skin elasticity and hydration. In elderly patients, this is often associated with dehydration, which occurs when the body loses more fluids than it takes in. As skin loses its moisture, it becomes less pliable, leading to a noticeable decrease in turgor. In contrast, fluid volume excess would typically result in increased turgor, while conditions like hypertension and pitting edema do not directly correlate with skin turgor changes. Thus, decreased skin turgor is most consistent with dehydration.

C. difficile is a spore-forming bacterium that can survive on surfaces and is resistant to alcohol-based hand sanitizers. Therefore, thorough handwashing with soap and water is essential to physically remove the spores from the hands, reducing the risk of transmission. This practice is crucial for both the patient and family members to prevent the spread of infection, especially in healthcare settings where hygiene is paramount. Educating them on the importance of proper hand hygiene can significantly lower the risk of reinfection and protect others from exposure.

A serum potassium level of 3.0 mEq/L indicates hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Lisinopril, an ACE inhibitor, and hydrochlorothiazide, a diuretic, can both contribute to lower potassium levels. Immediate intervention is necessary to prevent potential life-threatening consequences associated with low potassium, including muscle weakness and heart rhythm disturbances. Monitoring and correcting potassium levels is crucial in patients on these medications.

Injecting insulin directly into a vein is not recommended as it can lead to rapid absorption and potential hypoglycemia, which can be dangerous. Insulin is intended to be injected into subcutaneous tissue, where it is absorbed more gradually, allowing for better blood sugar control. Proper injection techniques, including site rotation and angle, are crucial for effective diabetes management and preventing complications. Therefore, this statement indicates a misunderstanding of safe insulin administration practices.

Airborne precautions are necessary for patients exhibiting symptoms such as a productive cough, night sweats, and fever, which may indicate a contagious respiratory infection like tuberculosis. This type of isolation is essential to prevent the transmission of pathogens that can be spread through airborne particles. Healthcare workers and visitors must wear appropriate respiratory protection, and the patient should be placed in a negative pressure room to minimize the risk of spreading the infection to others in the healthcare setting.

Elevating the head of the bed helps improve lung expansion and oxygenation, making it easier for the patient to breathe. Encouraging deep breathing and coughing can help mobilize secretions and clear the airways, which is particularly important when crackles are present, indicating fluid or mucus in the lungs. This intervention promotes better ventilation and reduces the risk of complications, making it the most appropriate choice in this situation.

In cases of medication errors, the nurse who administers the medication is typically held legally liable because they are responsible for verifying the medication and ensuring its correct administration. This includes checking the patient’s identity, the medication’s appropriateness, and potential allergies. While other parties, like the pharmacy or physician, may share some responsibility, the nurse's direct action in giving the wrong medication places the primary legal responsibility on them. This principle emphasizes the importance of accountability in nursing practice.

In Maslow's Hierarchy of Needs, physiological needs are the most fundamental requirements for human survival, including air, water, food, and shelter. In nursing care, addressing these needs is crucial as they form the foundation for all other needs. If a patient's physiological needs are not met, they cannot progress to higher levels of psychological or emotional well-being, making it the top priority in providing effective care. Meeting these basic needs ensures that patients are stable enough to engage in further therapeutic interventions.

Maintaining an oxygen saturation above 95% directly addresses the issue of ineffective airway clearance, as adequate oxygenation is essential for effective respiratory function. This goal ensures that the patient is receiving sufficient oxygen, which is critical for overall health and recovery. Other options, while important, do not specifically target the airway clearance issue as effectively as ensuring optimal oxygen saturation levels.

For effective use of a metered-dose inhaler (MDI), it's crucial to exhale fully to clear the lungs, allowing for a deeper inhalation of the medication. Inhaling slowly while pressing the canister ensures that the medication is delivered effectively into the lungs. Holding the breath for 10 seconds allows time for the medication to be absorbed into the lung tissue, maximizing its therapeutic effect. This technique enhances drug delivery and improves the patient's response to treatment.

The ventrogluteal injection site is identified by locating the anterior superior iliac spine and the greater trochanter of the femur. This landmark is preferred for intramuscular injections as it is situated away from major nerves and blood vessels, reducing the risk of complications. By placing the heel of the hand on the greater trochanter and pointing the thumb toward the anterior superior iliac spine, the injection site can be easily located in the gluteal muscle. This technique ensures safe and effective administration of medications.

Monitoring daily weight and restricting fluid intake are critical interventions for a patient with fluid volume excess. Daily weight checks help assess fluid retention and guide treatment decisions, while fluid restriction prevents further overload. These actions prioritize patient safety and effective management of fluid balance, reducing the risk of complications such as edema or heart failure. Other options, like encouraging fluid intake or administering IV fluids, would exacerbate the condition, making them inappropriate choices in this scenario.

To convert Fahrenheit to Celsius, the formula °C = (°F − 32) × 5/9 is used. Substituting the given temperature of 102.2°F into the formula:

°C = (102.2 − 32) × 5/9
= 70.2 × 5/9
≈ 39.0°C.

Thus, when 102.2°F is converted to Celsius, it results in approximately 39.0°C, indicating a significant fever.

Measuring and recording vital signs is a fundamental task that falls within the scope of practice for Nursing Assistive Personnel (NAP). This task requires basic skills and knowledge, making it suitable for delegation. It allows the nurse to focus on more complex tasks, such as assessments and care planning, while ensuring that vital signs are monitored regularly. In contrast, initial assessments, medication administration, and care plan development require a higher level of clinical judgment and expertise, which are not appropriate for NAPs.

A pH level of 0–4 indicates that the aspirate is acidic, which is typical for gastric contents. When verifying the placement of a nasogastric tube, a low pH confirms that the tube is correctly positioned in the stomach rather than in the lungs or intestines, where the pH would be higher. Thus, checking for a pH of 0–4 helps ensure safe and effective feeding, minimizing the risk of aspiration and other complications.

To safely remove Personal Protective Equipment (PPE), it's essential to follow the correct order to minimize contamination risk. Gloves should be removed first to prevent transferring pathogens to the hands. Next, the gown is taken off, followed by goggles, which protect the eyes. Finally, the mask is removed last to avoid inhaling any contaminants that may be present. This sequence helps ensure that the wearer is not exposed to harmful substances during the removal process, maintaining safety and hygiene.
