The nurse is caring for a client with heart failure.
Which of these prescribed medications places the client at risk for cardiogenic shock?
Nadolol.
Captopril.
Digoxin.
Hydrochlorothiazide.
The Correct Answer is A
Choice A rationale
Nadolol is a beta-blocker that can decrease heart rate and contractility, which can potentially exacerbate heart failure and lead to cardiogenic shock.
Choice B rationale
Captopril is an angiotensin-converting enzyme (ACE) inhibitor that is often used in the treatment of heart failure. It works by relaxing blood vessels and reducing the workload of the heart.
Choice C rationale
Digoxin is a cardiac glycoside that is used to treat heart failure and certain heart arrhythmias. It works by increasing the force of the heart’s contractions, which can improve heart function.
Choice D rationale
Hydrochlorothiazide is a diuretic that is often used in the treatment of heart failure. It works by helping the body get rid of excess fluid, which can reduce the workload of the heart.

Correct Answer is A
Explanation
Choice A rationale
Restricted activity can help reduce intestinal activity, thereby decreasing inflammation and allowing for tissue healing within the gastrointestinal tract.
Choice B rationale
While controlling diarrhea episodes is an important aspect of managing Crohn’s disease, it is not the primary purpose of activity restriction.
Choice C rationale
Promoting the healing process is a crucial aspect of managing Crohn’s disease. However, the primary purpose of activity restriction is to reduce intestinal activity, which in turn can promote healing.
Choice D rationale
Decreasing abdominal pain is an important aspect of managing Crohn’s disease, but it is not the primary purpose of activity restriction.
Correct Answer is ["1.8"]
Explanation
The client weighs 132 pounds. To convert pounds to kilograms, divide the weight in pounds by
2.2. So, the client’s weight in kilograms is: Step 1: 132 pounds ÷ 2.2 = 60 kg The prescription for dantrolene is 1.5 mg/kg. To find out how many milligrams the client should receive, multiply the client’s weight in kilograms by the dosage in mg/kg: Step 2: 60 kg × 1.5 mg/kg = 90 mg The vial is reconstituted to yield a concentration of 50 mg/mL. To find out how many mL the nurse should administer, divide the total dosage in milligrams by the concentration in mg/mL: Step 3: 90 mg ÷ 50 mg/mL = 1.8 mL So, the nurse should administer 1.8 mL of dantrolene.
