ATI Pathophysiology Exam 2
1. A nurse is providing care for a 44-year-old male client who is admitted with a diagnosis of fever of unknown origin (FUO). Which characteristic of the client's history is most likely to have a bearing on his current diagnosis?
- A. The client is a smoker.
- B. The client has a history of IV drug use.
- C. The client was treated for an STD 2 years ago.
- D. The client has a family history of cardiac disease.
Correct answer: B
Rationale: A history of IV drug use is significant in cases of fever of unknown origin, as it increases the risk of infections like endocarditis, which can present with persistent fever. Smoking (Choice A) is not directly linked to FUO. While a history of STD treatment (Choice C) may be relevant, it is less likely to be associated with FUO compared to IV drug use. Family history of cardiac disease (Choice D) is not typically a primary factor in the diagnosis of FUO.
2. 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.
3. 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: The correct answer is D: Palpable kidneys. Polycystic kidney disease often leads to the development of multiple fluid-filled cysts within the kidneys, causing them to enlarge. Enlarged kidneys can be palpated during a physical examination. Choices A, B, and C are incorrect. Suprapubic pain is not a typical clinical manifestation of polycystic kidney disease. Periorbital edema is more commonly associated with conditions like nephrotic syndrome or heart failure. Low serum creatinine level is not expected in patients with renal impairment due to polycystic kidney disease; instead, elevated serum creatinine levels are more likely.
4. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What critical contraindication should the nurse review with the patient?
- A. Use of nitrates
- B. Use of antihypertensive medications
- C. History of hypertension
- D. History of peptic ulcer disease
Correct answer: A
Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, which can lead to a dangerous drop in blood pressure. Choice B (Use of antihypertensive medications) is incorrect because antihypertensive medications are not a critical contraindication for sildenafil use. Choice C (History of hypertension) is incorrect as it is not a contraindication for sildenafil; in fact, sildenafil is sometimes used in patients with hypertension. Choice D (History of peptic ulcer disease) is also incorrect as it is not a critical contraindication for sildenafil use.
5. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?
- A. Crossed-extensor reflex
- B. Flexor reflex
- C. Withdrawal reflex
- D. Stretch reflex
Correct answer: C
Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.
