1. What is the best intervention for a patient experiencing hypoxia?

A. Administer oxygen
B. Reposition the patient
C. Provide humidified air
D. Provide chest physiotherapy

Correct answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

2. A nurse is caring for an adult client who has prescriptions for multiple medications. Which of the following is an age-related change that increases the risk for adverse effects from these medications?

A. Rapid gastric emptying
B. Prolonged medication half-life
C. Increased medication elimination
D. Decreased medication sensitivity

Correct answer: B

Rationale: The correct answer is B: Prolonged medication half-life. As clients age, their metabolism tends to slow down, leading to a prolonged half-life of medications in the body. This extended presence of drugs can increase the risk for adverse effects as the substances accumulate. Choice A, rapid gastric emptying, is not an age-related change and actually decreases the time medications spend in the stomach, potentially reducing their effectiveness. Choice C, increased medication elimination, is not an age-related change either; in fact, aging can lead to decreased renal function, affecting drug elimination. Choice D, decreased medication sensitivity, is not an age-related change that directly increases the risk for adverse effects; rather, it may lead to requiring higher doses for effectiveness but does not inherently increase the risk of adverse effects.

3. A nurse is assessing a client who is postoperative following a thyroidectomy. Which of the following findings is the priority for the nurse to report?

A. Calcium level of 9.0 mg/dL
B. Serum sodium level of 138 mEq/L
C. Respiratory rate of 18/min
D. Stridor

Correct answer: D

Rationale: Stridor is a high-pitched sound that indicates airway obstruction and is the priority finding to report following a thyroidectomy. In this situation, airway compromise is a critical concern that requires immediate intervention to ensure adequate oxygenation. While calcium level (Choice A) and serum sodium level (Choice B) are important assessments post-thyroidectomy, they do not represent an immediate threat to the client's airway. A respiratory rate of 18/min (Choice C) falls within the normal range and does not indicate an immediate risk to the client's airway compared to the presence of stridor.

4. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

A. Serum calcium
B. Blood glucose
C. Serum protein
D. Serum albumin

Correct answer: D

Rationale: The correct answer is D, Serum albumin. Serum albumin levels are a good indicator of the nutritional effectiveness of total parenteral nutrition (TPN). Monitoring serum albumin levels helps assess the client's overall protein status and nutritional adequacy. Choices A, B, and C are not direct indicators of the effectiveness of TPN therapy. Serum calcium levels may be affected by other factors, blood glucose monitoring is more relevant for clients with diabetes or those receiving insulin therapy, and serum protein is not as specific as serum albumin in evaluating TPN effectiveness.

5. Which electrolyte imbalance is most concerning for a patient on furosemide?

A. Hypokalemia
B. Hyponatremia
C. Hyperkalemia
D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss through increased urinary excretion, making hypokalemia the most concerning electrolyte imbalance. Hyponatremia (Choice B) is not typically associated with furosemide use. Hyperkalemia (Choice C) is less likely due to furosemide's potassium-wasting effect. Hypercalcemia (Choice D) is not a common electrolyte imbalance seen with furosemide.
