Nursing Elites

1. A patient has a parenteral nutrition infusion of 25% dextrose. A student nurse asks the nurse why a peripherally inserted central catheter was inserted. Which response by the nurse is most appropriate?

• A. There is a decreased risk for infection when 25% dextrose is infused through a central line.
• B. The prescribed infusion can be given much more rapidly when the patient has a central line.
• C. The 25% dextrose is hypertonic and will be more rapidly diluted when given through a central line.
• D. The required blood glucose monitoring is more accurate when samples are obtained from a central line.

Correct answer: C

Rationale: The 25% dextrose solution is hypertonic. Shrinkage of red blood cells can occur when solutions with dextrose concentrations greater than 10% are administered IV. Blood glucose testing is not more accurate when samples are obtained from a central line. The infection risk is higher with a central catheter than with peripheral IV lines. Hypertonic or concentrated IV solutions are not given rapidly.

2. A patient has a serum calcium level of 7.0 mEq/L. Which assessment finding is most important for the nurse to report to the health care provider?

• A. The patient is experiencing laryngeal stridor.
• B. The patient complains of generalized fatigue.
• C. The patient has not had a bowel movement for 4 days.
• D. The patient has numbness and tingling of the lips.

Correct answer: A

Rationale: The correct answer is A - 'The patient is experiencing laryngeal stridor.' Hypocalcemia can cause laryngeal stridor, which may lead to respiratory arrest. Rapid action is required to correct the patient’s calcium level to prevent a life-threatening situation. Choices B, C, and D are also symptoms of hypocalcemia, but laryngeal stridor takes precedence due to its potential to quickly progress to a critical condition.

3. A patient receives 3% NaCl solution for correction of hyponatremia. Which assessment is most important for the nurse to monitor while the patient is receiving this infusion?

• A. Lung sounds
• B. Urinary output
• C. Peripheral pulses
• D. Peripheral edema

Correct answer: A

Rationale: The correct answer is A: Lung sounds. Hypertonic solutions like 3% NaCl can cause water retention, leading to fluid excess. Monitoring lung sounds is crucial as crackles may indicate pulmonary edema, a serious manifestation of fluid excess. While monitoring urinary output, peripheral pulses, and peripheral edema are also important when administering hypertonic solutions, they do not provide immediate clues to acute respiratory or cardiac decompensation like lung sounds.

4. The father of an 11-year-old client reports to the nurse that the client has been wetting the bed since the passing of his mother and is concerned. Which action is most important for the nurse to take?

• A. Reassure the father that it is normal for a pre-teen to wet the bed during times of stress
• B. Inform the father that nocturnal emissions are abnormal and his son is developmentally delayed
• C. Inform the father that it is most important to let the son know that bedwetting is normal after trauma
• D. Refer the father and the client to a psychologist

Correct answer: D

Rationale: It is common for children to experience bedwetting as a response to severe trauma, such as losing a parent. Referring the father and the client to a psychologist is crucial in this situation to help the child cope with the loss and address any underlying emotional issues. Choice A is incorrect as bedwetting in this context is likely related to the trauma rather than puberty. Choice B is incorrect as nocturnal emissions are not abnormal and do not relate to bedwetting. Choice C is incorrect because the focus should be on addressing the emotional impact of the trauma rather than specifically discussing bedwetting.

5. After receiving change-of-shift report, which patient should the nurse assess first?

• A. Patient with a serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping
• B. Patient with a serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water
• C. Patient with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes
• D. Patient with a serum phosphorus level of 4.5 mg/dL who has multiple soft tissue calcium-phosphate precipitates

Correct answer: C

Rationale: The correct answer is patient C with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes. The low magnesium level and neuromuscular irritability suggest that the patient may be at risk for seizures, which are life-threatening. Assessing and addressing this patient's condition promptly is crucial to prevent complications. Patients A, B, and D have mild electrolyte disturbances or symptoms that require attention, but they are not at immediate risk for life-threatening complications like seizures, unlike patient C.
