Correct Answer: C

Rationale: The correct answer is C: Acquired immunity. Acquired immunity occurs when an individual is given a vaccine or immunization to develop antibodies. This type of immunity is specific and develops after exposure to an antigen. Innate immunity (choice A) is the body's natural defense system present at birth. Passive immunity (choice B) is temporary immunity passed from one individual to another. Natural immunity (choice D) refers to immunity that is not gained through medical intervention or deliberate exposure.

Correct Answer: B

Rationale: The correct answer is B. Nitroglycerin tablets should be stored in a cool, dark place to maintain their potency. Storing them correctly ensures that they remain effective when needed. Choices A, C, and D are incorrect. Taking one tablet every hour is not the correct dosing regimen for nitroglycerin. Nitroglycerin is usually taken as needed at the onset of chest pain, with specific instructions from the healthcare provider. Taking nitroglycerin with food or antacids is not necessary, as it is usually placed under the tongue for rapid absorption.

Correct Answer: C

Rationale: The correct answer is C: 'Monitor for liver function.' Duloxetine is an antidepressant medication, not an antipsychotic, so choice A is incorrect. One of the common side effects of duloxetine is weight gain, making choice B incorrect. Choice D, stating that duloxetine has no side effects, is inaccurate as all medications have the potential for side effects. Monitoring liver function is crucial with duloxetine because it can impact liver function, emphasizing the importance of regular checks to ensure the client's safety.

Correct Answer: B

Rationale: The correct answer is B: Blood pressure. When caring for a client with a history of hypertension, monitoring blood pressure is crucial as it allows the nurse to assess the effectiveness of management and adjust treatment if necessary. Monitoring fluid intake (Choice A) is important for conditions like heart failure, but in hypertension, the focus is primarily on blood pressure. Monitoring serum potassium levels (Choice C) is relevant in clients taking certain medications like diuretics, and weight (Choice D) is important for overall health assessment but is not the primary parameter to monitor in hypertension.

Correct Answer: A

Rationale: The correct answer is A. Doxazosin can cause first-dose orthostatic hypotension, which may lead to dizziness or fainting when the client stands up too quickly. The nurse should advise the client to change positions slowly and lie down if dizziness occurs to prevent falls and other injuries. Choice B is incorrect because while the client can continue normal activities, caution should be taken with position changes. Choice C is incorrect as doxazosin does not interact with dairy products. Choice D is incorrect as there is no need to avoid green leafy vegetables specifically while taking doxazosin.
