A proton pump inhibitor like Prilosec is used to block secretions of gastric acid. It works by inhibiting the enzyme responsible for producing acid in the stomach, thereby reducing the amount of acid produced. This can be helpful in treating conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions where excessive gastric acid secretion is a problem. By blocking the secretion of gastric acid, Prilosec can help alleviate symptoms such as heartburn, acid reflux, and inflammation of the esophagus (esophagitis). It does not specifically prevent the feeling of fullness from meals or the rupture of a hiatal hernia.

The abbreviation "ac" indicates that a drug is to be administered prior to meals. This stands for "ante cibum" in Latin, which translates to "before meals" in English.

300 milligrams is equal to 0.3 grams. This is because there are 1000 milligrams in a gram, so to convert milligrams to grams, we divide by 1000. Therefore, 300 milligrams divided by 1000 equals 0.3 grams.

To calculate the cc/hr to program into the IV pump, we need to determine the rate at which the Heparin drip is administered. The physician ordered a Heparin bolus of 5,000 units IV, which is given as a one-time dose. The remaining Heparin is prepared as a drip at a rate of 500 units per hour. The standard Heparin preparation is 25,000 units in 500 ml. Therefore, to administer 500 units per hour, we need to infuse 10 ml per hour (500 units / 25,000 units = 0.02, 0.02 x 500 ml = 10 ml/hr). Hence, the correct answer is 10 cc/hr.

To convert cc's to ounces, we can use the conversion factor of 1 cc = 0.0338 oz. Therefore, to find how many ounces are equivalent to 60 cc's, we can multiply 60 by 0.0338. The result is approximately 2.028 oz. Since the answer options are rounded, the closest option to 2.028 oz is 2.0 oz.

Protamine Sulfate (Answer B) is correct. Vitamin K is the antidote for Coumadin (Warfarin).

When administering an aminoglycoside antibiotic, the nurse monitors the client's serum creatinine levels. Aminoglycosides can cause nephrotoxicity, which is kidney damage, and monitoring serum creatinine levels helps to assess kidney function. If the serum creatinine levels increase, it may indicate kidney damage, and the nurse can take appropriate actions such as adjusting the dosage or discontinuing the medication to prevent further harm to the client's kidneys. Monitoring serum potassium and sodium levels is important for other medications, and monitoring red blood cell count is not directly related to the administration of aminoglycoside antibiotics.

Spironolactone (Aldactone) is classified as a potassium sparing diuretic because it works by blocking the action of aldosterone in the kidneys, which helps to prevent the reabsorption of potassium and promote the excretion of sodium and water. This leads to increased urine production without causing excessive loss of potassium, making it a potassium sparing diuretic. Furosemide (Lasix), Hydrochlorothiazide (HydroDiuril), and Ethacrynic acid (Edecrin) are not classified as potassium sparing diuretics.

Gentamycin is an antibiotic that can cause serious side effects. Ototoxicity refers to damage to the inner ear, leading to hearing loss or balance problems. Nephrotoxicity refers to kidney damage. These two reactions are considered serious because they can have long-term effects on a patient's health.

The correct answer is to remove the ointment previously applied. This is because nitroglycerin ointment is typically applied in a thin layer and needs to be removed before applying a new dose. This ensures that the previous dose does not accumulate and cause an overdose. Removing the old ointment also allows for better absorption of the new dose and prevents potential skin irritation or reactions.

If more than 3 tablets are administered sublingual 15 minutes apart, additional medical intervention will be needed.

Hyperkalemia is not a clinically significant adverse reaction from Prednisone administration. Prednisone is a corticosteroid medication that can cause various side effects. Increased appetite with subsequent weight gain, hyperglycemia (high blood sugar levels), and increased serum cholesterol are known side effects of Prednisone. However, hyperkalemia, which refers to high levels of potassium in the blood, is not typically associated with Prednisone use.
