Nursing Elites

1. A client with a severe head injury is admitted to the intensive care unit (ICU). Which finding should the nurse report to the healthcare provider immediately?

• A. Urine output of 100 mL/hour.
• B. Intracranial pressure (ICP) of 20 mm Hg.
• C. Respiratory rate of 12 breaths/minute.
• D. Mean arterial pressure (MAP) of 70 mm Hg.

Correct answer: B

Rationale: An Intracranial Pressure (ICP) of 20 mm Hg is at the upper limit of normal and may indicate increased intracranial pressure, which is a critical finding in a client with a severe head injury. Elevated ICP can lead to further brain damage and must be addressed promptly to prevent complications such as herniation. Monitoring and managing ICP are crucial in the care of patients with head injuries in the ICU.

2. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

3. What is the primary action of digoxin when prescribed to a patient with heart failure?

• A. Increase heart rate
• B. Decrease cardiac output
• C. Strengthen cardiac contractions
• D. Lower blood pressure

Correct answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.

4. A patient with type 1 diabetes is prescribed insulin glargine. What is the primary characteristic of this insulin?

• A. Rapid-acting
• B. Intermediate-acting
• C. Long-acting
• D. Short-acting

Correct answer: C

Rationale: Insulin glargine is classified as a long-acting insulin. It is designed to provide a consistent level of insulin over approximately 24 hours, helping to keep blood glucose levels stable throughout the day. This long duration of action makes it suitable for basal insulin replacement in patients with type 1 diabetes, providing a background level of insulin to mimic the body's natural release of insulin between meals and overnight.

5. A 68-year-old man with a history of diabetes, hypertension, and coronary artery disease (s/p coronary artery bypass graft two years ago) presents to the emergency room with fevers and left-sided abdominal pain. His physical examination reveals a temperature of 101.5°F, pulse 96, and blood pressure of 135/80. His abdomen is soft with moderate left lower quadrant tenderness. There is no rebound or guarding. Bowel sounds are present. A CT scan is done which reveals inflammation around an area of the left colon. The next step in his workup/management should be

• A. Antibiotic therapy with ciprofloxacin and metronidazole
• B. Referral for urgent colonoscopy
• C. Referral to a surgeon for immediate hemicolectomy
• D. Barium enema

Correct answer: A

Rationale: The patient's presentation is consistent with diverticulitis without evidence of perforation or abscess formation on CT scan. During acute infections, procedures like barium enema and colonoscopy should be avoided to prevent the risk of perforation. Urgent surgery is not indicated initially. The appropriate next step is to start antibiotic therapy aimed at gram-negative aerobes and anaerobes, such as ciprofloxacin and metronidazole, which are the initial treatment of choice for diverticulitis.
