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 is receiving a 3% saline continuous IV infusion for hyponatremia. Which assessment data will require the most rapid response by the nurse?

• A. The patient’s radial pulse is 105 beats/minute.
• B. There is sediment and blood in the patient’s urine.
• C. The blood pressure increases from 120/80 to 142/94.
• D. There are crackles audible throughout both lung fields.

Correct answer: D

Rationale: Crackles throughout both lungs suggest that the patient may be experiencing pulmonary edema, a life-threatening adverse effect of hypertonic solutions. The increased pulse rate and blood pressure and the presence of sediment and blood in the urine should also be reported, but they are not as immediately dangerous as the presence of fluid in the alveoli, which compromises gas exchange and can lead to respiratory failure.

3. When assessing a pregnant patient with eclampsia who is receiving IV magnesium sulfate, which finding should the nurse report to the health care provider immediately?

• A. The bibasilar breath sounds are decreased.
• B. The patellar and triceps reflexes are absent.
• C. The patient has been sleeping most of the day.
• D. The patient reports feeling 'sick to my stomach.'

Correct answer: B

Rationale: The correct answer is B because the absence of patellar and triceps reflexes indicates potential magnesium toxicity, requiring immediate intervention. Nausea and lethargy are common side effects of elevated magnesium levels and should be reported, but they are not as critical as the loss of deep tendon reflexes. Decreased breath sounds suggest the need for coughing and deep breathing to prevent atelectasis, which is important but not as urgent as addressing magnesium toxicity.

4. The nurse is preparing to send a client to the cardiac catheterization lab for an angioplasty. Which client report is most important for the nurse to explore further prior to the procedure?

• A. Experiences facial swelling after eating crab
• B. Reports left chest wall pain prior to the admission
• C. Verbalizes a fear of being in a confined space
• D. Drank a glass of water

Correct answer: A

Rationale: The correct answer is A. Allergy to shellfish can indicate a potential allergy to iodine, which is used in contrast dye for the procedure. This must be explored further to prevent an allergic reaction. Choice B is not directly related to the angioplasty procedure. Choice C pertains to claustrophobia, which can be addressed but is not directly related to the safety of the procedure. Choice D is a routine activity and does not pose a risk to the client during the procedure.

5. A patient who is taking a potassium-wasting diuretic for the treatment of hypertension complains of generalized weakness. It is most appropriate for the nurse to take which action?

• A. Assess for facial muscle spasms.
• B. Ask the patient about loose stools.
• C. Suggest that the patient avoid orange juice with meals.
• D. Ask the healthcare provider to order a basic metabolic panel.

Correct answer: D

Rationale: Generalized weakness is a sign of hypokalemia, a potential side effect of potassium-wasting diuretics. By requesting a basic metabolic panel, the nurse can assess the patient's potassium levels. Facial muscle spasms are associated with hypocalcemia, not hypokalemia. Advising the patient to avoid orange juice, which is high in potassium, would be counterproductive if the patient is hypokalemic. Loose stools are typically seen in hyperkalemia, not hypokalemia.
