Extract:
Question 1 of 5
Which assessment finding will the nurse expect for a patient with the following laboratory values: sodium 145 mEq/L, potassium 45 mq, calcium 45 mg/dL?
Correct Answer: D
Rationale: Hypocalcemia (low calcium) causes tingling in extremities due to nerve excitability. Hyperkalemia may cause weakness, but not specifically quadriceps, and light-headedness or decreased reflexes are less directly linked.
Question 2 of 5
A nurse is teaching a client who is obese and has obstructive sleep apnea how to decrease the number of nightly apneic episodes. Which of the following client statements indicates an understanding of the teaching?
Correct Answer: C
Rationale: Weight loss is a key factor in reducing obstructive sleep apnea episodes, as excess weight around the neck increases airway obstruction risk. Sleeping on the back worsens apnea, sleeping pills relax throat muscles, and humidifiers don’t directly reduce episodes.
Question 3 of 5
A nurse is caring for a client who sustained blood loss. Which of the following is a manifestation of hypovolemia?
Correct Answer: D
Rationale: A weak pulse is a primary manifestation of hypovolemia due to reduced circulating blood volume, leading to decreased perfusion pressure. Hypovolemia causes hypotension, tachycardia, and possibly dyspnea in severe cases, but weak pulse is most direct.
Question 4 of 5
A nurse is assessing a client who has obstructive sleep apnea. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Morning headaches are common in obstructive sleep apnea due to intermittent hypoxia and hypercapnia. Nausea, hypotension, and constipation are not typical findings.
Question 5 of 5
A nurse is caring for a client who has hypernatremia and requires IV fluid therapy due to his NPO status. Which of the following solutions should the nurse prepare to infuse for this client?
Correct Answer: C
Rationale: 0.45% sodium chloride (half-normal saline) is hypotonic, providing free water to dilute excess sodium in hypernatremia. Lactated Ringer’s and D5NS contain sodium, worsening hypernatremia, and D10W is for calories, not electrolytes.
