Pharmacology and the Nursing Process 10th Edition Test Bank

Correct Answer: D

Rationale: The correct answer is D: �I will receive parenteral vitamin B12 therapy for the rest of my life.� This statement is correct because pernicious anemia is a lifelong condition requiring ongoing vitamin B12 supplementation. Patients with pernicious anemia lack intrinsic factor, which is needed to absorb vitamin B12 from food. Therefore, they need lifelong B12 therapy to prevent complications such as anemia and neurological damage. Choices A, B, and C are incorrect because they suggest a limited duration of therapy. Pernicious anemia is a chronic condition that necessitates continuous treatment. Choice A implies therapy until signs and symptoms disappear, which may not address the underlying cause of the deficiency. Choice B mentions therapy until vitamin B12 levels normalize, which may not prevent recurrence. Choice C suggests monthly therapy for a fixed period, which may not be sufficient for lifelong management.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to describe the type of reaction. This is the first action the nurse should take because it is essential to assess the severity of the latex allergy to determine the appropriate precautions and interventions. By asking the patient to describe the type of reaction, the nurse can gather crucial information to ensure patient safety. Choice A is incorrect because placing the patient in isolation is not necessary for a latex allergy. Choice C is incorrect as terminating the interview prematurely is not appropriate without gathering important information about the allergy. Choice D is incorrect because documenting the allergy is important, but assessing the type of reaction should be the initial priority.

Correct Answer: A

Rationale: The correct answer is A because shampooing the hair thoroughly helps remove oil and dirt, which can interfere with the CT scan results. By having clean hair, the scan can produce clearer images. Choice B is incorrect because some preparation is needed for a CT scan, especially regarding cleanliness. Choice C is incorrect as giving a cleansing enema and fluids until 8 AM is not necessary for a CT scan of the head. Choice D is incorrect as shaving the scalp and attaching electrodes are not part of routine preparation for a CT scan.

Correct Answer: C

Rationale: Rationale: - A: Diuretics are not necessary before the test and may affect test results. - B: Dehydration is not recommended before the test as it can impact cardiac function. - C: Medication to relieve cough is necessary to reduce any potential interference with the scan. - D: Administering analgesics is not required for the test and may not be relevant to the client's condition.

Correct Answer: A

Rationale: The correct answer is A: Smoking. Smoking presents the greatest threat for respiratory disease due to the harmful chemicals in tobacco that can damage the lungs and lead to conditions like COPD and lung cancer. Smoking is a well-known risk factor for various respiratory issues. Exposure to radiation (B) can increase cancer risk but is not as directly linked to respiratory diseases. High-fat diet (C) may impact overall health but is not a primary risk factor for respiratory diseases. Alcohol consumption (D) can contribute to respiratory issues, but smoking is considered the most significant risk factor.
