A nurse is assessing a client with hypokalemia and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first?
- A. Assess the client's respiratory rate, rhythm, and depth.
- B. Measure the client's pulse and blood pressure.
- C. Document findings and monitor the client.
- D. Call the healthcare provider.
Correct Answer: A
Rationale: The correct action for the nurse to take first is to assess the client's respiratory rate, rhythm, and depth (Choice A). Diminished handgrip strength in a client with hypokalemia could indicate potential respiratory muscle weakness, which can lead to respiratory distress or failure. By assessing the client's respiratory status, the nurse can determine if immediate intervention is needed to support breathing.
Choice B is incorrect because measuring the client's pulse and blood pressure may not address the underlying issue of respiratory muscle weakness. Choice C is incorrect as it delays potential life-saving interventions by simply documenting findings. Choice D is incorrect as calling the healthcare provider should come after addressing the client's immediate respiratory needs.

A nurse is caring for a client who has just experienced a 90-second tonic-clonic seizure. The clients arterial blood gas values are pH 6.88, PaO2 50 mm Hg, PaCO2 60 mm Hg, and HCO3 22 mEq/L. Which action should the nurse take first?
- A. . Apply oxygen by mask or nasal cannula
- B. Apply a paper bag over the clients nose and mouth.
- C. Administer 50 mL of sodium bicarbonate intravenously.
- D. Administer 50 mL of 20% glucose and 20 units of regular insulin.
Correct Answer: A
Rationale: The correct answer is A: Apply oxygen by mask or nasal cannula. The client is experiencing respiratory acidosis due to inadequate ventilation and oxygenation during the seizure. Providing oxygen will help improve oxygenation and correct the respiratory acidosis. This is the priority to address the immediate physiological need.
Choice B is incorrect as applying a paper bag can lead to rebreathing of carbon dioxide, worsening the respiratory acidosis. Choice C is incorrect as sodium bicarbonate is not indicated in this situation and can potentially worsen the acid-base imbalance. Choice D is incorrect as administering glucose and insulin is not relevant to correcting the respiratory acidosis.
A nurse is caring for a client who is experiencing moderate metabolic alkalosis. Which action should the nurse take?
- A. Monitor daily hemoglobin and hematocrit values.
- B. Administer furosemide (Lasix) intravenously.
- C. Encourage the client to take deep breaths.
- D. Teach the client fall prevention measures.
Correct Answer: D
Rationale: The correct answer is D: Teach the client fall prevention measures. In metabolic alkalosis, the client may experience muscle weakness and confusion, increasing the risk of falls. Teaching fall prevention measures is essential to ensure the client's safety. Monitoring hemoglobin and hematocrit values (A) is not directly related to managing metabolic alkalosis. Administering furosemide (B) is not appropriate for metabolic alkalosis. Encouraging deep breaths (C) may not address the underlying cause of the alkalosis.
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.
You are the nurse evaluating a newly admitted patients laboratory results, which include several values that are
outside of reference ranges. Which of the following would cause the release of antidiuretic hormone (ADH)?
- A. Increased serum sodium
- B. Decreased serum potassium
- C. Decreased hemoglobin
- D. Increased platelets
Correct Answer: A
Rationale: The correct answer is A: Increased serum sodium. High serum sodium levels trigger the release of antidiuretic hormone (ADH) from the pituitary gland to help retain water in the body and maintain fluid balance. This is a physiological response to prevent further dehydration. Decreased serum potassium (choice B), decreased hemoglobin (choice C), and increased platelets (choice D) do not directly stimulate the release of ADH. Hence, they are incorrect choices in this scenario.
1.A nurse prepares to insert a peripheral venous catheter in an older adult client. Which action should the nurse take to protect the clients skin during this procedure?
- A. Lower the extremity below the level of the heart.
- B. Apply warm compresses to the extremity.
- C. Tap the skin lightly and avoid slapping.
- D. Place a washcloth between the skin and tourniquet
Correct Answer: D
Rationale: The correct answer is D: Place a washcloth between the skin and tourniquet. This step helps protect the client's skin by providing a barrier between the tourniquet and the skin, reducing the risk of skin irritation or damage. Lowering the extremity below the heart (A) can increase venous pressure and make it harder to insert the catheter. Warm compresses (B) can dilate blood vessels and increase the risk of bruising. Tapping the skin lightly (C) can irritate the skin and is unnecessary for skin protection.
