A healthcare professional caring for a client who has been receiving intravenous diuretics suspects that the client is experiencing a deficient fluid volume. Which assessment finding would the healthcare professional note in a client with this condition?
- A. Lung congestion
- B. Decreased hematocrit
- C. Increased blood pressure
- D. Decreased central venous pressure (CVP)
Correct Answer: D
Rationale: Decreased central venous pressure (CVP) is the correct assessment finding in a client with deficient fluid volume. This is because a decrease in CVP indicates reduced blood volume returning to the heart, which is consistent with hypovolemia. Lung congestion (Choice A) would be more indicative of fluid volume excess, not deficiency. Decreased hematocrit (Choice B) may be seen in conditions such as anemia but is not specific to deficient fluid volume. Increased blood pressure (Choice C) is not typically associated with deficient fluid volume; in fact, hypovolemia often leads to decreased blood pressure.

A client with type 2 DM is prescribed metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?
- A. Take the medication with meals.
- B. Take the medication on an empty stomach.
- C. Avoid taking the medication if you miss a meal.
- D. Take the medication before bedtime.
Correct Answer: A
Rationale: The correct instruction when taking metformin (Glucophage) is to take the medication with meals. Taking metformin with meals helps to reduce gastrointestinal side effects and improve absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of gastrointestinal side effects. Choice C is incorrect because missing a meal does not mean the medication should be avoided; the client should still take it with the next meal. Choice D is incorrect because there is no specific recommendation to take metformin before bedtime.
Which of the following ethical principles is involved when a healthcare provider allows a patient to refuse treatment?
- A. Autonomy
- B. Nonmaleficence
- C. Beneficence
- D. Justice
Correct Answer: A
Rationale: The correct answer is A: Autonomy. Autonomy is the ethical principle that respects an individual's right to make their own decisions, including the right to refuse treatment. This principle acknowledges the patient's self-governance and independence in making choices about their own healthcare. Choice B, Nonmaleficence, refers to the ethical principle of doing no harm and ensuring patient safety. Choice C, Beneficence, involves promoting the patient's well-being and acting in their best interest. Choice D, Justice, pertains to fairness and equitable distribution of healthcare resources.
The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?
- A. Decreased blood glucose levels
- B. Decreased urine ketones
- C. Increased serum bicarbonate
- D. Increased anion gap
Correct Answer: D
Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.
A female client with physical findings suggestive of a hyperpituitary condition undergoes an extensive diagnostic workup. Test results reveal a pituitary tumor, necessitating a transsphenoidal hypophysectomy. The evening before the surgery, Nurse Jacob reviews preoperative and postoperative instructions provided to the client earlier. Which postoperative instruction should the nurse emphasize?
- A. You must lie flat for 24 hours after surgery.
- B. You must avoid coughing, sneezing, and blowing your nose.
- C. You must restrict your fluid intake.
- D. You must report ringing in your ears immediately.
Correct Answer: B
Rationale: Following a transsphenoidal hypophysectomy, it is crucial to avoid activities such as coughing, sneezing, and blowing the nose to prevent an increase in intracranial pressure or the risk of cerebrospinal fluid leakage. Coughing, sneezing, or nose blowing can strain the surgical site, potentially leading to complications. Lying flat for 24 hours is not typically required after this surgery. Fluid intake should be encouraged to prevent dehydration. Ringing in the ears is not a common complication associated with this type of surgery.
When teaching a male client diagnosed with type 1 diabetes mellitus how diet and exercise affect insulin requirements, Nurse Joy should include which guideline?
- A. You'll need more insulin when you exercise or increase your food intake.
- B. You'll need less insulin when you exercise or reduce your food intake.
- C. You'll need less insulin when you increase your food intake.
- D. You'll need more insulin when you exercise or decrease your food intake.
Correct Answer: B
Rationale: When a person with type 1 diabetes exercises, it typically lowers blood glucose levels. As a result, insulin needs are reduced when exercise or food intake is decreased. Choice A is incorrect because more insulin is not typically needed when exercise or food intake is increased. Choice C is incorrect because increasing food intake would generally require more insulin to cover the additional glucose from the food. Choice D is incorrect as decreasing food intake usually leads to a lower need for insulin.
