1. When evaluating the success of adding raltegravir to the drug regimen of a 42-year-old female patient with HIV, which laboratory value should the nurse prioritize?
- A. The patient's C-reactive protein levels
- B. The patient's erythrocyte sedimentation rate (ESR)
- C. The patient's viral load
- D. The patient's CD4 count
Correct answer: C
Rationale: The correct answer is C: The patient's viral load. In HIV management, monitoring the viral load is crucial to assess the effectiveness of antiretroviral therapy. A decrease in viral load indicates the treatment's success in controlling the HIV infection. Choices A, B, and D are less relevant in this context. C-reactive protein levels and erythrocyte sedimentation rate are markers of inflammation and non-specific indicators of infection, not specifically for HIV. CD4 count is important but not as immediate for evaluating the response to the newly added medication compared to monitoring the viral load.
2. What can multiple dark bands on the nails indicate?
- A. They are considered a normal variant.
- B. They can be associated with malignant melanoma.
- C. They are indicative of a nail fungus.
- D. They are associated with aging.
Correct answer: B
Rationale: Multiple dark bands on the nails can be associated with malignant melanoma, a serious type of skin cancer. While dark bands on the nails can sometimes be a normal variant, they should not be ignored as they could also be a sign of a serious condition like melanoma. Nail fungus typically presents with different symptoms such as thickened, discolored, or brittle nails. Dark bands on the nails are not directly associated with aging.
3. A male patient with erectile dysfunction has asked for a prescription for sildenafil (Viagra). Before giving this medication, the nurse should assess for which of the following conditions?
- A. History of peptic ulcer disease
- B. Use of nitrates
- C. Recent history of a stroke
- D. History of hypertension
Correct answer: B
Rationale: The correct answer is B: Use of nitrates. Sildenafil should not be used by patients taking nitrates due to the risk of severe hypotension. Nitrates can potentiate the hypotensive effects of sildenafil, leading to a significant drop in blood pressure. Assessing for the use of nitrates is crucial to avoid this potentially dangerous interaction. Choices A, C, and D are incorrect because they are not specifically contraindications for the use of sildenafil. While a history of hypertension should be considered, it is not as critical as the use of nitrates when prescribing sildenafil.
4. Which of the following is a clinical manifestation in a patient with renal impairment associated with polycystic kidney disease?
- A. Suprapubic pain
- B. Periorbital edema
- C. Low serum creatinine level
- D. Palpable kidneys
Correct answer: D
Rationale: Palpable kidneys are a common clinical manifestation in patients with polycystic kidney disease due to the enlarged kidneys with multiple cysts. Suprapubic pain is not typically associated with this condition. Periorbital edema is more commonly seen in conditions like nephrotic syndrome. A low serum creatinine level is not a typical finding in renal impairment, as impaired kidneys usually lead to an elevated serum creatinine level.
5. Macular degeneration occurs as a result of:
- A. loss of lens accommodation
- B. detachment of the retina
- C. increased intraocular pressure
- D. impaired blood supply leading to cellular waste accumulation and ischemia
Correct answer: D
Rationale: Macular degeneration is a condition that affects the macula, a part of the retina responsible for central vision. It is primarily caused by impaired blood supply to the macula, leading to cellular waste accumulation and ischemia. This results in the death of photoreceptor cells and ultimately vision loss. Choices A, B, and C are incorrect because macular degeneration is not related to the loss of lens accommodation, detachment of the retina, or increased intraocular pressure. The correct answer directly addresses the underlying pathophysiology of macular degeneration.
