Chapter 19 : Adrenergic-Blocking Drugs Questions
Question 1 of 5
The nurse is screening a patient who will be taking a nonspecific/nonselective beta blocker. Which condition, if present, may cause serious problems if the patient takes this medication?
Correct Answer: D
Rationale: Nonselective beta blockers can cause bronchoconstriction by blocking beta-2 receptors in the lungs, worsening asthma. They are used to treat angina and hypertension, and glaucoma is not a contraindication.
Question 2 of 5
A patient is experiencing Class II heart failure. The nurse expects which beta blocker to be ordered for this patient?
Correct Answer: B
Rationale: Carvedilol is indicated for heart failure due to its combined beta and alpha-blocking effects, which reduce cardiac workload and improve outcomes. Atenolol, labetalol, and esmolol are not typically used for heart failure.
Question 3 of 5
During a teaching session about self-monitoring while taking a beta blocker at home, the nurse has taught the patient to take his apical pulse daily for 1 minute. If the pulse rate decreases to less than 60 beats/min, the nurse will instruct the patient to do which of these?
Correct Answer: A
Rationale: A pulse rate below 60 beats/min may indicate excessive cardiac depression from beta blockers, requiring prescriber notification for potential dose adjustment. Reducing the dose, continuing without consultation, or skipping doses are unsafe.
Question 4 of 5
A patient is in the clinic for a follow-up visit 3 months after starting a beta blocker for treatment of hypertension. During this visit, his blood pressure is 169/98 mm Hg, and he eventually confesses that he stopped taking this medicine 2 months ago because of an 'embarrassing problem.' What problem did the patient most likely experience with this medication that caused him to stop taking it?
Correct Answer: D
Rationale: Impotence is a known adverse effect of beta blockers and may lead to non-compliance. Urge incontinence, dizziness, and excessive flatus are not commonly associated with beta blockers.
Question 5 of 5
A patient has a new prescription for tamsulosin as treatment for benign prostatic hyperplasia. The nurse is checking his current medication list and will contact the prescriber regarding a potential interaction if the patient is also taking which drug?
Correct Answer: B
Rationale: Sildenafil can interact with tamsulosin, an alpha blocker, causing additive hypotensive effects, increasing the risk of severe hypotension. Levothyroxine, omeprazole, and aspirin do not have significant interactions with tamsulosin.
