Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

Correct Answer: B

Rationale: Step-by-step rationale: 1. CD4+ cells are a type of white blood cell crucial for immune function. 2. HIV targets and destroys CD4+ cells, leading to immune system damage. 3. Measuring CD4+ levels helps determine the extent of this damage. 4. Therefore, the correct answer is B. Summary: A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose. C: Level of the viral load - Measured separately from CD4+ levels. D: Resistance to antigens - CD4+ levels do not directly indicate resistance.

Correct Answer: D

Rationale: The correct answer is D: Fever. Following splenectomy, patients are at risk for OPSI due to impaired immune response. Fever is a key symptom of infection and should alert the nurse to this possibility. Bruising around the operative site (A) is expected post-surgery. Pain (B) is common after surgery and may not specifically indicate OPSI. Irritability (C) is a vague symptom and not specific to OPSI. In summary, fever is the most concerning symptom as it can indicate an underlying infection in a postsplenectomy patient.

Correct Answer: A

Rationale: The correct answer is A: Obtain his oral temperature. Seizure precautions typically include avoiding putting objects in the mouth to prevent injury during a seizure. Taking an oral temperature involves placing an object in the mouth, which could pose a risk if a seizure occurs. Choices B, C, and D are not contraindicated as they do not directly involve potential risks during a seizure. Allowing the patient to wear his own clothing, encouraging personal hygiene, and promoting mobility are safe practices that do not increase the risk of harm during a seizure.

Correct Answer: D

Rationale: The correct answer is D. Epinephrine, when applied locally, constricts blood vessels, reducing blood flow and slowing down bleeding. This vasoconstrictive effect helps control nosebleeds effectively. Choice A is incorrect because although epinephrine can raise blood pressure, it is not the primary mechanism for treating nosebleeds. Choice B is incorrect as epinephrine's bronchodilation effect is not relevant in this context. Choice C is incorrect as while promoting blood clotting is beneficial, epinephrine primarily acts by vasoconstriction to control bleeding.

Correct Answer: C

Rationale: Step 1: Classic full-blown AIDS presents with tumors and opportunistic infections due to severe immune system suppression. Step 2: These manifestations occur when CD4 cell count drops significantly, leading to inability to fight infections. Step 3: Persistent generalized lymphadenopathy (Choice A) can be seen in early HIV infection, not necessarily in full-blown AIDS. Step 4: Sudden weight loss, fever, and malaise (Choice B) are non-specific symptoms seen in various conditions, not specific to AIDS. Step 5: Fever, weight loss, night sweats, and diarrhea (Choice D) are common symptoms but lack the specificity of tumors and opportunistic infections seen in classic full-blown AIDS.
