Correct Answer: B

Rationale: The priority when administering etanercept (Enbrel) to a client with rheumatoid arthritis is to monitor white blood cell counts and platelet counts. Etanercept can lead to infections and pancytopenia, making it crucial to assess for changes in these blood parameters to detect any potential complications early on.

Correct Answer: D

Rationale: The correct instruction for a client prescribed losartan (Cozaar) is to report any swelling of the lips or face. Losartan can cause angioedema, which is a serious side effect that requires immediate medical attention. Clients do not need to avoid potassium-rich foods unless specifically instructed by their healthcare provider. Taking the medication with grapefruit juice is not recommended as it can interact with certain medications. Additionally, monitoring blood pressure regularly is important, but it should not be limited to a weekly basis; blood pressure should be monitored as per the healthcare provider's recommendation.

Correct Answer: C

Rationale: Intranasal desmopressin can cause a runny or stuffy nose as a side effect due to its mode of administration through the nasal passages.

Correct Answer: D

Rationale: Sucralfate is a gastric protectant that forms a protective coating over the ulcer. Administering sucralfate 1 hour before meals and at bedtime is important to create a barrier that protects the ulcer from gastric acid and mechanical irritation. This timing allows sucralfate to effectively coat the ulcer site and provide the desired therapeutic effect, enhancing its efficacy in promoting ulcer healing and symptom relief.

Correct Answer: C

Rationale: The normal serum calcium level ranges from 8.6 to 10.0 mg/dL. In hypercalcemia, as seen in this client, Calcitonin (Miacalcin) is used to decrease plasma calcium levels by inhibiting bone resorption. Calcium gluconate and calcium chloride are typically used for hypocalcemia, not hypercalcemia. Large doses of vitamin D should be avoided in hypercalcemia as they can exacerbate hypercalcemia by increasing calcium absorption from the intestines.
