Nursing Process Questions

Correct Answer: C

Rationale: The correct answer is C: 125 mL/h. To calculate the infusion rate per hour, we divide the total volume (1000 mL) by the total time in hours (8 hours). 1000 mL / 8 hours = 125 mL/h. This ensures a consistent and accurate infusion rate throughout the 8-hour period. Choice A (80 mL/h) is incorrect because it underestimates the infusion rate. Choice B (100 mL/h) is incorrect because it does not divide the total volume by the total time correctly. Choice D (150 mL/h) is incorrect because it overestimates the infusion rate.

Correct Answer: A

Rationale: The correct answer is A because successful treatment of diabetes insipidus aims to reduce excessive urine output and dehydration. A fluid intake of less than 2,500mL in 24 hours indicates proper control of fluid balance. Choice B is incorrect because urine output of more than 200mL/hour suggests ongoing excessive fluid loss, which is not indicative of successful treatment. Choice C is incorrect as a blood pressure of 90/50mmHg is low and may indicate hypotension, which is not a specific indicator of successful diabetes insipidus treatment. Choice D is incorrect because a pulse rate of 126 beats/min is not a direct marker of diabetes insipidus treatment success. In summary, the correct indicator of successful treatment of diabetes insipidus is a reduction in fluid intake, option A, as it signifies improved fluid balance and hydration status.

Correct Answer: C

Rationale: The correct answer is C. Hormonal imbalances are the primary cause of BPH in aging males. As men age, testosterone levels decrease and estrogen levels may increase relative to testosterone, leading to prostate gland growth. This is why hormonal imbalances are more likely the cause of BPH in older males. Explanation of other choices: A: Chronic infection of the urinary tract does not directly cause BPH, although it can lead to similar symptoms such as urinary frequency and urgency. B: Chronic cigarette smoking is not a direct cause of BPH, although it can contribute to overall prostate health and exacerbate symptoms. D: Chronic obstruction of the bladder due to stone is a separate condition from BPH, although it can cause similar urinary symptoms.

Correct Answer: D

Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates because pneumonia causes inflammation and fluid accumulation in the alveoli, leading to impaired gas exchange. The nurse correctly identified the underlying respiratory issue. A: Ineffective breathing pattern related to pneumonia is incorrect as it focuses on the pattern of breathing rather than the physiological problem causing the breathing difficulty. B: Risk for infection related to chest x-ray procedure is incorrect as the patient already has a diagnosis of pneumonia, so the focus should be on managing the existing condition. C: Risk for deficient fluid volume related to dehydration is incorrect as there is no indication of dehydration in the question stem. In summary, the nurse's diagnosis of Impaired gas exchange related to alveolar-capillary membrane changes is the most appropriate as it addresses the respiratory issue caused by pneumonia and lower lobe infiltrates.

Correct Answer: B

Rationale: The correct answer is B (Lifetime dependency on hormone replacement) because after hypophysectomy (removal of the pituitary gland), patients will no longer produce essential hormones like growth hormone, thyroid-stimulating hormone, etc. Therefore, they will require lifelong hormone replacement therapy to maintain normal bodily functions. A: Abnormal distribution of body hair is not directly related to hypophysectomy. C: While fluid intake may be important post-surgery, it is not the primary focus of teaching. D: There is typically no need for repeat surgical procedures after a hypophysectomy, as it is a one-time surgery to address specific issues. In summary, choice B is correct as it directly addresses the long-term implications of the surgery on hormone production and the need for replacement therapy, while the other choices are not directly relevant to the post-operative care of hypophysectomy patients.
