1. A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?
- A. Metabolic acidosis
 - B. Metabolic alkalosis
 - C. Respiratory acidosis
 - D. Respiratory alkalosis
 
Correct answer: A
Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.
2. A male client expresses concern about how a hypophysectomy will affect his sexual function. Which of the following statements provides the most accurate information about the physiologic effects of hypophysectomy?
- A. Removing the source of excess hormone should restore the client's libido, erectile function, and fertility.
 - B. Potency will be restored, but the client will remain infertile.
 - C. Fertility will be restored, but impotence and decreased libido will persist.
 - D. Exogenous hormones will be needed to restore erectile function after the adenoma is removed.
 
Correct answer: A
Rationale: Choice A is the most accurate statement regarding the physiologic effects of hypophysectomy on sexual function. The client's sexual problems are directly related to excessive hormone levels. Removing the source of excess hormone secretion through hypophysectomy should allow the client to return to a normal physiologic pattern, which includes restoring libido, erectile function, and fertility. Choices B, C, and D are incorrect. Choice B incorrectly states that the client will remain infertile, which is not necessarily true after a hypophysectomy. Choice C inaccurately suggests that fertility will be restored while impotence and decreased libido will persist, which is not aligned with the expected outcomes of hypophysectomy. Choice D is incorrect because exogenous hormones are typically not needed to restore erectile function after the adenoma is removed; rather, the removal of the source of excessive hormone secretion should address the sexual function concerns.
3. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?
- A. Iso-osmolar
 - B. Hypo-osmolar
 - C. Hyperosmolar
 - D. Isotonic
 
Correct answer: C
Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.
4. When planning care for a client newly diagnosed with open-angle glaucoma, the nurse identifies a priority nursing problem of 'visual sensory/perceptual alterations.' This problem is based on which etiology?
- A. Blurred distance vision
 - B. Limited eye movement
 - C. Decreased peripheral vision
 - D. Photosensitivity
 
Correct answer: C
Rationale: The correct answer is 'C: Decreased peripheral vision.' Open-angle glaucoma leads to a gradual loss of peripheral vision due to damage to the optic nerve. This loss of peripheral vision is a hallmark sign of the condition and a primary reason for the visual sensory/perceptual alterations experienced by the client. Blurred distance vision (choice A) may occur but is not the priority nursing problem. Limited eye movement (choice B) and photosensitivity (choice D) are not typically associated with the sensory/perceptual alterations seen in open-angle glaucoma.
5. When conducting discharge teaching for a client diagnosed with diverticulosis, which diet instruction should the nurse include?
- A. Eat a high-fiber diet and increase fluid intake.
 - B. Have small frequent meals and sit up for at least two hours after meals.
 - C. Eat a bland diet and avoid spicy foods.
 - D. Eat a soft diet with increased intake of milk and milk products.
 
Correct answer: A
Rationale: A high-fiber diet with increased fluid intake is the most appropriate diet instruction for a client diagnosed with diverticulosis. High-fiber foods help prevent constipation and promote bowel regularity, reducing the risk of complications such as diverticulitis. Adequate fluid intake is crucial to soften stool and aid in digestion. Choice B, having small frequent meals and sitting up after meals, may be beneficial for some gastrointestinal conditions but is not specific to diverticulosis. Choice C, eating a bland diet and avoiding spicy foods, is not necessary for diverticulosis management. Choice D, consuming a soft diet with increased milk and milk products, may worsen symptoms in diverticulosis due to the potential for increased gas production and bloating.
