Question 1 of 5

A nurse is assessing clients on a medical-surgical unit. Which clients are at increased risk for hypophosphatemia? (Select all that do not apply.)

A. A 36-year-old who is malnourished B. A 42-year-old with uncontrolled diabetes C. A 76-year-old who is prescribed antacids D. 50-year-old with hyperparathyroidism

Correct Answer: C

Rationale: The correct answer is C because antacids contain aluminum or magnesium, which can bind with phosphorus and decrease its absorption, leading to hypophosphatemia. Malnourishment (choice A) can cause hypophosphatemia due to inadequate intake, uncontrolled diabetes (choice B) is associated with hyperphosphatemia, and hyperparathyroidism (choice D) can lead to hyperphosphatemia due to increased calcium levels.

Question 2 of 5

A gerontologic nurse is teaching students about the high incidence and prevalence of dehydration in older adults. What factors contribute to this phenomenon? Select all that do not apply.

A. Decreased kidney mass B. Decreased renal blood flow C. Decreased excretion of potassium D. Increased conservation of sodium

Correct Answer: D

Rationale: The correct answer is D: Increased conservation of sodium. Older adults tend to have an increased conservation of sodium, leading to fluid retention and decreased fluid intake, which can contribute to dehydration. A: Decreased kidney mass is incorrect because it is a factor that can contribute to decreased kidney function but not directly linked to dehydration. B: Decreased renal blood flow can impact kidney function but is not a direct cause of dehydration in older adults. C: Decreased excretion of potassium is not a factor that directly contributes to dehydration in older adults.

Question 3 of 5

A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

A. Depth of respirations B. Bowel sounds C. Grip strength D. Electrocardiography

Correct Answer: A

Rationale: The correct assessment for the nurse to complete first is A: Depth of respirations. Potassium and magnesium levels are crucial electrolytes that can affect cardiac function. Hypokalemia (low potassium) and hypomagnesemia (low magnesium) can lead to cardiac dysrhythmias. Checking the depth of respirations can provide valuable information on the client's respiratory status and potential respiratory distress due to electrolyte imbalances. This assessment takes precedence as addressing respiratory issues promptly is essential to prevent further complications. Assessing bowel sounds (B), grip strength (C), and electrocardiography (D) are important but not as immediate as assessing respiratory status in this scenario.

Question 4 of 5

A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

A. Administer topical lidocaine to the site. B. Place warm compresses on the site. C. . Administer prescribed oral pain medication. D. Massage the site with scented oils.

Correct Answer: B

Rationale: The correct answer is B: Place warm compresses on the site. Warm compresses can help increase blood flow, reduce pain, and promote healing at the site of inflammation. The warmth can help dilate blood vessels, increasing circulation to the area and promoting the removal of inflammatory substances. This can help alleviate pain and reduce swelling. Administering topical lidocaine (choice A) may not address the underlying cause of pain and redness. Administering oral pain medication (choice C) may be necessary for severe pain but may not directly address the local inflammation. Massaging the site with scented oils (choice D) can potentially introduce more irritants and should be avoided in cases of inflammation.

Question 5 of 5

. A nurse is planning care for a nephrology patient with a new nursing graduate. The nurse states, A patient in renal failure partially loses the ability to regulate changes in pH. What is the cause of this partial inability?

A. The kidneys regulate and reabsorb carbonic acid to change and maintain pH. B. The kidneys buffer acids through electrolyte changes C. The kidneys regenerate and reabsorb bicarbonate to maintain a stable pH. D. The kidneys combine carbonic acid and bicarbonate to maintain a stable pH.

Correct Answer: C

Rationale: Rationale: C is correct because in renal failure, the kidneys lose the ability to regenerate and reabsorb bicarbonate, which is essential for maintaining a stable pH level in the body. B is incorrect because the kidneys primarily regulate pH by controlling bicarbonate levels, not through electrolyte changes. A is incorrect because the kidneys do not regulate carbonic acid in the same way. D is incorrect as it does not accurately describe the process of pH regulation in the kidneys.
