Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: B

Rationale: The correct answer is B: Collect his urine for 12 hours. This instruction is given because the Schilling test involves collecting urine over a specific time period to measure the absorption of vitamin B12. A is incorrect because fasting is not necessary. C is incorrect as enema is not required. D is incorrect as emptying the bladder is not part of the test procedure.

Correct Answer: B

Rationale: The correct answer is B because the nurse should always prioritize communication with the patient, especially when the patient is alert and oriented. Speaking only to the patient's daughter could undermine the patient's autonomy and right to be involved in their care. It is important for the nurse to directly address the patient to gather accurate information and ensure patient-centered care. Making eye contact (A), leaning forward (C), and nodding periodically (D) are all appropriate communication techniques that show attentiveness and engagement with the patient, which are crucial in building rapport and trust.

Correct Answer: A

Rationale: The correct answer is A because compromised nutrition can lead to deficiencies in essential nutrients required for the production of blood cells and hemoglobin. Iron, vitamins, and minerals obtained from food are crucial for erythropoiesis and maintaining a healthy immune system. Without these nutrients, the body may struggle to produce an adequate amount of healthy red blood cells, leading to anemia and compromised immune function. Choice B is incorrect because excessive fat in the diet is not directly linked to interfering with the production of blood cells and hemoglobin. Choice C is incorrect as inconsistent dieting may affect overall health but is not specifically related to hematopoiesis. Choice D is incorrect because while iron and protein are important for blood cell production, excessive amounts of these elements are unlikely to interfere with the production of blood cells and hemoglobin.

Correct Answer: C

Rationale: The correct answer is C because it accurately defines a transient ischemic attack (TIA) as a temporary interruption in blood flow to the brain. This response demonstrates the nurse's knowledge and ability to provide accurate information to the family member. Option A is incorrect because it deflects the question to the doctor without providing any information. Option B is incorrect because it inaccurately states that TIA causes permanent brain damage, which is not true. Option D is also incorrect because it simply restates the abbreviation without providing any explanation of what TIA actually means.

Correct Answer: A

Rationale: The correct answer is A: White patches on the tonsils. Group A streptococci infection commonly presents with exudative tonsillitis, characterized by the presence of white patches or pus on the tonsils. This is due to the inflammatory response triggered by the bacteria. Hypertrophied tonsils (B), hemorrhage in the tonsils (C), and bleeding in the tonsils (D) are less likely to be visual signs of a streptococcal infection and are more indicative of other conditions or complications. Therefore, white patches on the tonsils are the most specific visual sign associated with group A streptococci tonsillar infection.
