Nursing Elites

1. A patient is admitted to the hospital with a diagnosis of primary hyperparathyroidism. A nurse checking the patient's lab results would expect which of the following changes in laboratory findings?

• A. Elevated serum calcium
• B. Low serum parathyroid hormone (PTH)
• C. Elevated serum vitamin D
• D. Low urine calcium

Correct answer: A

Rationale: In primary hyperparathyroidism, there is excess secretion of parathyroid hormone (PTH) leading to increased resorption of calcium from bones and decreased excretion of calcium by the kidneys. This results in elevated serum calcium levels. Elevated serum calcium is a hallmark characteristic of primary hyperparathyroidism, making it the correct answer. Low serum parathyroid hormone (PTH) (Choice B) is incorrect because primary hyperparathyroidism is associated with elevated PTH levels due to the malfunction of the parathyroid glands. Elevated serum vitamin D (Choice C) is incorrect because primary hyperparathyroidism is not typically associated with elevated vitamin D levels. Low urine calcium (Choice D) is incorrect as primary hyperparathyroidism leads to decreased calcium excretion by the kidneys, resulting in high levels of calcium in the urine.

2. A patient admitted to the hospital with myocardial infarction develops severe pulmonary edema. Which of the following symptoms should the nurse expect the patient to exhibit?

• A. Slow, deep respirations
• B. Stridor
• C. Bradycardia
• D. Air hunger

Correct answer: D

Rationale: In a patient with pulmonary edema following a myocardial infarction, the nurse should expect symptoms such as air hunger, anxiety, and agitation. Air hunger refers to the feeling of needing to breathe more deeply or more often. Other symptoms of pulmonary edema can include coughing up blood or bloody froth, orthopnea (difficulty breathing when lying down), and paroxysmal nocturnal dyspnea (sudden awakening with shortness of breath). Slow, deep respirations (Choice A) are not typical in pulmonary edema; these patients often exhibit rapid, shallow breathing due to the difficulty in oxygen exchange. Stridor (Choice B) is a high-pitched breathing sound often associated with upper airway obstruction, not typically seen in pulmonary edema. Bradycardia (Choice C), a slow heart rate, is not a characteristic symptom of pulmonary edema, which is more likely to be associated with tachycardia due to the body's compensatory response to hypoxia and increased workload on the heart.

3. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

• A. The patient is allergic to shellfish.
• B. The patient has a pacemaker.
• C. The patient suffers from claustrophobia.
• D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.

4. What is the most appropriate suggestion regarding the diet for an 18-month-old child experiencing mild diarrhea and 'mushy' stools, but tolerating fluids and solid foods?

• A. Applesauce, bananas, wheat toast
• B. Mashed potatoes with baked chicken
• C. Gelatin, strained cabbage, and custard
• D. Fluids only until the 'mushy' stools stop

Correct answer: B

Rationale: For a child with mild diarrhea who is tolerating fluids and solid foods, the most appropriate diet suggestion would be to continue feeding a normal diet to prevent dehydration, reduce stool frequency and volume, and hasten recovery. Foods that are well tolerated during diarrhea include bland but nutritional options like complex carbohydrates (rice, wheat, potatoes, cereals), yogurt with live cultures, cooked vegetables, and lean meats. Mashed potatoes with baked chicken provide a balance of nutrients and are easy on the digestive system. Options A and C contain foods that may worsen diarrhea; applesauce and gelatin can be high in sugars which can exacerbate diarrhea, and cabbage may be hard to digest for some individuals. Option D of offering fluids only can affect the child's nutritional status by not providing enough essential nutrients during the recovery period.

5. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?

• A. Stroke volume
• B. Cardiac output
• C. Venous pressure
• D. Left ventricular functioning

Correct answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.
