- A.
  
  Treats hypotention either by PO or IV
- B.
  
  Completely blocks cholergenic receptor sites leaing to an increase in BP
- C.
  
  Assessment shoul beware of DM, shock, CHF, asthma, and bronchospasms
- D.
  
  Baseline should include EEG, cardiac input, respiratory rate, and skin colour and temperature
- E.
  
  None of the above
Correct Answer
C. Assessment shoul beware of DM, shock, CHF, asthma, and bronchospasms

Explanation
INDICATIONS: hypertention. ACTIONS: competitively blocks alpha- an beta- receptor sites in the SNS leading to LOWER BLOOD PRESSURE. PHARMACOKINETICS: given by PO or IV. ADVERSE EFFECTS: Dizziness, vertigo, fatigue, gastric pain, flatulence, bronchospasm, dypnea, cough, and decrease exercise tolerance. ASSESSMENT should include allergies, bradycaria, heart blocks, shock, CHF, asthma, or DM. BASELINE should include skin colour, temperature, pulse, BP, cardiac output, ECG, respiration, aventitious sounds, and blood glucose levels and electrolytes (p. 493).

- A.
  
  Labetolol
- B.
  
  Atropine
- C.
  
  Bethanachol
- D.
  
  Dopamine
- E.
  
  None of the above
Correct Answer
C. Bethanachol

Explanation
BETHANECHOL. INDICATIONS: acute postoperative or postpartum non-obstructive urinary retention; neurogenic atony of the bladder with retention. ACTION: Acts directly on cholinergic receptors tomimic the effects of acetylcholine; increases tone of detrusor muscles and causes emptying of the bladder. Is given ORALLY. ADVERSE EFFECTS: Abdominal discomfort, salivation, nausea, vomiting, sweating, and flushing. ASSESSMENT would include bradycardia, vasomotor instability, peptic ulcer, obstructive urinary or GI diseases, asthma, parkinsonism or epilepsy. BASELINE ASSESSMENT includes skin colour, lesions, temperature; pulse, blood pressure, ECG; respirations, adventitious sounds; and urine output and bladder tone

- A.
  
  Atropine
- B.
  
  Labetolol
- C.
  
  Naloxone
- D.
  
  Mupricin
- E.
  
  Dopamine
Correct Answer
A. Atropine

Explanation

Which of the following is false about atropine?
- A.
  
  It can be a poison
- B.
  
  Assessment includes glaucoma, stenosing peptic ulcer, intestinal atony, paralytic ileus, GI obstruction, toxic megacolon; cardiac arrhythmias, tachycardia
- C.
  
  Baseline includes skin colour, lesions, temperature; affect, orientation, reflexes, pupil response; pulse, BP, ECG; respirations, adventidious sounds, urine output, and BS
- D.
  
  Is found in many natural products
- E.
  
  None of the above
Correct Answer
E. None of the above

Explanation
Atropine is a medication that can be toxic in high doses, making the statement "It can be a poison" true. The assessment for atropine includes various conditions such as glaucoma, stenosing peptic ulcer, intestinal atony, paralytic ileus, GI obstruction, toxic megacolon; cardiac arrhythmias, tachycardia, making the statement true. The baseline for atropine includes evaluating skin color, lesions, temperature; affect, orientation, reflexes, pupil response; pulse, BP, ECG; respirations, adventitious sounds, urine output, and BS, making the statement true. Atropine is found in many natural products, making the statement true. Therefore, none of the statements about atropine are false.
