Correct Answer: C

Rationale: The correct answer is C: Tachypnea. When caring for a client with pneumonia, the nurse should expect tachypnea, which is rapid breathing. This occurs due to decreased oxygenation and lung function. Bradycardia (A) is not typically associated with pneumonia; instead, tachycardia may be present. Hypertension (B) is not a common manifestation of pneumonia; instead, hypotension may occur due to sepsis. Hypothermia (D) is not a typical finding in pneumonia; fever or an elevated temperature is more common.

Correct Answer: A

Rationale: The correct answer is A: Serotonin syndrome. When a client takes St. John's wort, a herbal supplement, along with citalopram, a selective serotonin reuptake inhibitor (SSRI), there is a risk of developing serotonin syndrome. Serotonin syndrome is a potentially life-threatening condition characterized by symptoms such as confusion, agitation, fever, sweating, shivering, tremors, muscle rigidity, and in severe cases, seizures and coma. It is crucial for the nurse to monitor the client for these symptoms. Choices B, C, and D are incorrect because tardive dyskinesia is associated with long-term use of antipsychotic medications, pseudo-parkinsonism is a side effect of antipsychotic medications like haloperidol, and acute dystonia is a side effect of antipsychotic medications characterized by sustained muscle contractions.

Correct Answer: A

Rationale: The correct recommendation for a client with hypertension is to limit sodium intake to no more than 1,500 mg per day. This helps manage hypertension by reducing fluid retention and lowering blood pressure. Choice B is a good recommendation as well, but the primary focus for hypertension management in this scenario is limiting sodium. Choices C and D are incorrect as dairy products and carbohydrates are not directly linked to hypertension.

Correct Answer: A

Rationale: Correct answer: Applying zinc oxide ointment to the irritated area is the most appropriate action for diaper dermatitis. Zinc oxide is a barrier cream that helps protect the skin and promote healing. Choice B is incorrect because using store-bought baby wipes may contain chemicals or fragrances that can further irritate the skin. Choice C is incorrect as talcum powder can also worsen the condition by drying out the skin. Choice D is incorrect because a warm compress is not typically used for diaper dermatitis; it may provide relief for other conditions but is not the best option for diaper dermatitis.

Correct Answer: C

Rationale: The correct answer is C: Tachypnea. Anemia leads to decreased oxygen-carrying capacity due to low hemoglobin levels, prompting the body to increase respiratory rate to enhance oxygen uptake. Jaundice (choice A) is associated with liver issues, not anemia. Bradycardia (choice B) and Hypertension (choice D) are not typically expected findings in clients with anemia; instead, tachycardia may occur as the body compensates for the decreased oxygen delivery.
