1. A client with heart failure is prescribed digoxin. Which of the following findings should the nurse identify as an adverse effect of digoxin?

A. Constipation
B. Blurred vision
C. Nausea
D. Headache

Correct answer: B

Rationale: Blurred vision is a common adverse effect of digoxin and can indicate toxicity. Monitoring for visual changes is essential to prevent serious complications in clients taking digoxin.

2. What is the antidote for Warfarin?

A. Vitamin D
B. Vitamin C
C. Vitamin K
D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

3. To which pharmacologic classification does the drug propranolol belong?

A. Beta Blockers
B. Cholinergics
C. Immune globulins
D. Barbiturates

Correct answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.

4. A client is taking Desmopressin for Diabetes Insipidus. For which of the following adverse effects should the nurse monitor?

A. Hypovolemia
B. Hypercalcemia
C. Agitation
D. Headache

Correct answer: D

Rationale: Headache is an adverse effect that the nurse should monitor for in a client taking Desmopressin for Diabetes Insipidus. It can be an early sign of water intoxication, which is a potential complication of desmopressin therapy due to excessive water retention in the body.

5. Which adverse reaction poses the greatest life-threatening risk when taking Omeprazole?

A. Chest pain
B. Constipation
C. Clostridium difficile-associated diarrhea
D. Acute interstitial nephritis

Correct answer: C

Rationale: The most life-threatening adverse reaction associated with Omeprazole is Clostridium difficile-associated diarrhea. This condition can be severe and life-threatening due to the potential for dehydration, electrolyte imbalances, and complications such as toxic megacolon. Chest pain, constipation, and acute interstitial nephritis are potential side effects of Omeprazole but are not considered as life-threatening as Clostridium difficile-associated diarrhea. Monitoring for signs of this adverse reaction is crucial, and immediate medical attention should be sought if symptoms develop.
