1. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?

A. Sodium phosphate
B. Psyllium
C. Bisacodyl
D. Polyethylene glycol

Correct answer: A

Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.

2. Which of the following drugs is associated with hepatitis as a reaction?

A. Valproic acid
B. Quinidine
C. Isoniazid
D. Ethosuximide

Correct answer: C

Rationale: Hepatitis is a known side effect of isoniazid. It is important to monitor patients on isoniazid for signs of liver damage, including hepatitis, as part of their treatment regimen for tuberculosis.

3. When starting therapy with trastuzumab, which finding should the nurse instruct the client to report?

A. Dyspnea
B. Constipation
C. Tinnitus
D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Dyspnea. Dyspnea can indicate pulmonary toxicity, a severe adverse effect of trastuzumab. It is crucial for the client to report any breathing difficulties promptly to ensure timely intervention and prevent further complications. Choices B, C, and D are incorrect because constipation, tinnitus, and dry mouth are not commonly associated with trastuzumab therapy and are not indicative of serious adverse effects that require immediate attention.

4. Which of the following conditions is not treated with Methotrexate?

A. Sarcomas
B. Leukemias
C. Ectopic pregnancy
D. Rheumatic fever

Correct answer: D

Rationale: The correct answer is D. Methotrexate is not typically used to treat rheumatic fever, which is more commonly managed with antibiotics to eradicate the underlying infection. Methotrexate is commonly used in the treatment of conditions like sarcomas, leukemias, and ectopic pregnancies due to its anti-inflammatory and anti-cancer properties.

5. A client has a new prescription for Captopril for hypertension. The nurse should monitor the client for which of the following adverse effects of this medication?

A. Hypokalemia
B. Hypernatremia
C. Neutropenia
D. Bradycardia

Correct answer: C

Rationale: Neutropenia is a serious adverse effect associated with ACE inhibitors like Captopril. Neutropenia refers to a decreased level of neutrophils, which are important white blood cells in fighting infection. Monitoring the client's complete blood count (CBC) is essential to detect neutropenia early. Hypokalemia (Choice A) is more commonly associated with diuretics, not ACE inhibitors. Hypernatremia (Choice B) is an increase in sodium levels, not typically caused by Captopril. Bradycardia (Choice D) is not a common adverse effect of ACE inhibitors like Captopril.
