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. The nurse is caring for a newborn with a suspected diagnosis of imperforate anus. The nurse monitors the infant, knowing that which is a clinical manifestation associated with this disorder?

• A. Bile-stained fecal emesis
• B. The passage of currant jelly-like stools
• C. Failure to pass meconium stool in the first 24 hours after birth
• D. Sausage-shaped mass palpated in the upper right abdominal quadrant

Correct answer: C

Rationale: Imperforate anus is the incomplete development or absence of the anus in its normal position in the perineum. Failure to pass meconium stool within the first 24 hours after birth is a key clinical manifestation associated with this disorder. This finding should prompt further assessment to confirm the suspected diagnosis. Other assessment findings in imperforate anus may include absence or stenosis of the anal rectal canal, presence of an anal membrane, and an external fistula to the perineum. Options A, B, and D describe findings typically noted in intussusception, a different condition characterized by bowel obstruction and telescoping of the intestines that can present with bile-stained fecal emesis, the passage of currant jelly-like stools, and a sausage-shaped mass palpated in the upper right abdominal quadrant.

3. A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:

• A. Has increased airway obstruction.
• B. Has improved airway obstruction.
• C. Needs to be suctioned.
• D. Exhibits hyperventilation.

Correct answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

4. A patient is scheduled for a computed tomography (CT) of the chest with contrast media. Which assessment finding should the nurse immediately report to the health care provider?

• A. Patient is claustrophobic.
• B. Patient is allergic to shellfish.
• C. Patient recently used a bronchodilator inhaler.
• D. Patient is not able to remove a wedding band.

Correct answer: B

Rationale: The correct answer is that the patient is allergic to shellfish. This is crucial because the contrast media used in CT scans is iodine-based, and individuals with iodine allergies, such as those allergic to shellfish, are at risk of adverse reactions. It is important to identify and address this allergy to prevent potential complications. The other options do not directly impact the safety or effectiveness of the CT scan with contrast media. Claustrophobia can be managed with patient support, the recent use of a bronchodilator inhaler does not typically affect the CT procedure, and not being able to remove a wedding band is not a critical concern for the scan itself.

5. 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.
