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 client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is

• A. Surgical repair of a diseased coronary artery.
• B. Placement of an automatic internal cardiac defibrillator.
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow.
• D. Non-invasive radiographic examination of the heart.

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.

3. The patient who has two fractured ribs from an automobile accident is receiving discharge teaching. Which statement by the patient indicates effective teaching?

• A. I am going to buy a rib binder to wear during the day.
• B. I can take shallow breaths to prevent my chest from hurting.
• C. I should plan on taking the pain pills only at bedtime so I can sleep.
• D. I will use the incentive spirometer every hour or two during the day.

Correct answer: D

Rationale: The correct answer is, 'I will use the incentive spirometer every hour or two during the day.' After sustaining rib fractures, it is crucial to prevent complications like atelectasis and pneumonia by practicing deep breathing and coughing. Using the incentive spirometer helps in maintaining lung expansion and preventing respiratory issues. Buying a rib binder could restrict chest expansion and hinder deep breathing efforts, increasing the risk of atelectasis. Taking shallow breaths may not effectively expand the lungs, leading to potential respiratory complications. Relying solely on pain medication at bedtime may not adequately address the need for lung expansion and prevention of respiratory complications during the day.

4. A nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?

• A. Slow pulse rate
• B. Weight gain
• C. Decreased systolic pressure
• D. Irregular WBC lab values

Correct answer: B

Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.

5. What is the cause of meningitis that is fatal in half of the infected patients?

• A. Virus
• B. Bacteria
• C. Fungus
• D. Noninfectious agent

Correct answer: B

Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.
