Chapter 19 : Adrenergic-Blocking Drugs Questions
Question 1 of 5
The teaching for a patient who is taking tamsulosin to reduce urinary obstruction due to benign prostatic hyperplasia will include which of these?
Correct Answer: C
Rationale: Tamsulosin, an alpha blocker, can cause orthostatic hypotension, so patients should stand up slowly to avoid dizziness and falls. Fluid restriction is not required, timing with breakfast is not necessary, and tamsulosin causes hypotension, not hypertension.
Question 2 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 3 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 4 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 5 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.
