foundation of nursing questions and answers

Correct Answer: D

Rationale: The correct answer is D: Pneumocystis pneumonia. This is the most common life-threatening infection in HIV-positive patients with low CD4+ counts. Pneumocystis pneumonia is caused by the opportunistic pathogen Pneumocystis jirovecii, which can lead to severe respiratory distress and mortality in immunocompromised individuals. The other choices, A: Salmonella infection, B: Mycobacterium tuberculosis, and C: Clostridium difficile, can also cause infections in HIV-positive patients, but they are not as commonly associated with life-threatening complications in this population compared to Pneumocystis pneumonia. It is crucial for the nurse to prioritize assessment for signs and symptoms of Pneumocystis pneumonia in this patient to promptly intervene and prevent further complications.

Correct Answer: C

Rationale: The correct answer is C because anesthetics used during surgery can decrease bladder contractility, leading to urinary retention. By inserting an indwelling catheter, the nurse ensures proper drainage of urine and prevents bladder distention. This helps to maintain the patient's comfort and prevent complications such as urinary retention and potential bladder injury. Choice A is incorrect because inserting a catheter is not primarily to prevent uncontrollable voiding during surgery. Choice B is incorrect as local trauma does not promote excessive urine incontinence necessitating catheterization. Choice D is incorrect because the primary purpose of catheter insertion is not to prevent interruption of the procedure by bathroom breaks.

Correct Answer: D

Rationale: The correct answer is D because cleansing the meatus with circular strokes starting at the meatus and moving outward helps prevent the introduction of bacteria into the urethra. This technique minimizes the risk of urinary tract infections. Holding the shaft at a 60-degree angle (A) or with the dominant hand (B) is not necessary for catheter insertion. Cleansing the meatus 3 times with the same cotton ball (C) can introduce more bacteria and is not recommended.

Correct Answer: D

Rationale: The correct answer is D because it emphasizes the importance of consistent and correct condom use in preventing HIV transmission. Here's the rationale: 1. Abstinence is the most effective way to prevent HIV, but since the teen is sexually active, abstinence may not be feasible for her. 2. Using condoms consistently and correctly is the next best method for preventing HIV transmission during sexual activity. 3. Choice A is incorrect because it implies that using condoms is not effective, which is not true. 4. Choice B is incorrect because it only mentions female condoms, while both male and female condoms can be effective in preventing HIV. 5. Choice C is incorrect because while new prevention methods are being researched, the established method of consistent condom use remains the most effective.

Correct Answer: A

Rationale: The correct answer is A: Abdominal palpation. Palpating the abdomen can potentially cause rupture of the liver in patients with HELLP syndrome due to increased risk of liver hematoma. This can lead to severe bleeding and compromise the patient's condition. Checking deep tendon reflexes (C), auscultation of the heart and lungs (D), and venous sample of blood (B) are safe assessments that do not pose a risk of exacerbating the patient's condition. It is crucial to prioritize patient safety and avoid interventions that can harm the patient, making avoiding abdominal palpation the correct choice in caring for a patient with HELLP syndrome.
