Nursing Elites

1. Which client should the nurse recognize as most likely to experience sleep apnea?

• A. Middle-aged female who takes a diuretic nightly.
• B. Obese older male client with a short, thick neck.
• C. Adolescent female with a history of tonsillectomy.
• D. School-aged male with a history of hyperactivity disorder.

Correct answer: B

Rationale: The correct answer is B. Sleep apnea is characterized by pauses in breathing during sleep, often due to a collapsed or blocked airway. Obesity and having a short, thick neck are risk factors for sleep apnea because excess fat around the neck can obstruct the airway. Option A (middle-aged female who takes a diuretic nightly) does not present as a common risk factor for sleep apnea. Option C (adolescent female with a history of tonsillectomy) may have had tonsils removed, which could reduce the risk of sleep apnea. Option D (school-aged male with a history of hyperactivity disorder) is not directly associated with an increased risk of sleep apnea.

2. A client has been scheduled for magnetic resonance imaging (MRI). For which of the following conditions, a contraindication to MRI, does the nurse check the client’s medical history?

• A. Pancreatitis
• B. Pacemaker insertion
• C. Type 1 diabetes mellitus
• D. Chronic airway limitation

Correct answer: B

Rationale: The correct answer is B: Pacemaker insertion. Patients with metal devices or implants are contraindicated for MRI. These include pacemakers, orthopedic hardware, artificial heart valves, aneurysm clips, and intrauterine devices. These metal objects can be affected by the strong magnetic field of the MRI, leading to serious risks for the patient. Pancreatitis (choice A), Type 1 diabetes mellitus (choice C), and chronic airway limitation (choice D) are not contraindications to MRI based on the presence of metal objects. Therefore, the nurse should be particularly concerned about pacemaker insertion when reviewing the client's medical history prior to an MRI.

3. After a urography, a client is instructed by a nurse. Which instruction should the nurse include in this client’s discharge teaching?

• A. Avoid direct contact with your urine for 24 hours until the dye clears.
• B. You may experience dribbling of urine for several weeks post-procedure.
• C. Drink at least 3 liters of fluids today to assist in dye elimination.
• D. Your skin may turn slightly yellow from the dye used in this procedure.

Correct answer: C

Rationale: It is important for the client to increase fluid intake to aid in the rapid elimination of the potentially nephrotoxic dye used in urography. This instruction will help prevent any adverse effects related to the dye. Choices A, B, and D are incorrect because the dye used in urography is not radioactive, so there is no need to avoid direct contact with urine, urine dribbling is not a common post-procedure occurrence, and the dye should not cause the client's skin to change color.

4. The patient is receiving a high dose of intravenous azithromycin to treat an infection and taking acetaminophen for pain. The nurse should expect to review which lab values when monitoring for this drug’s side effects?

• A. Complete blood counts
• B. Electrolytes
• C. Liver enzymes
• D. Urinalysis

Correct answer: C

Rationale: When a patient is receiving a high dose of intravenous azithromycin, which is a macrolide antibiotic, in combination with acetaminophen, a potentially hepatotoxic drug, the nurse should monitor liver enzymes. High doses of macrolides when taken with hepatotoxic drugs like acetaminophen can lead to hepatotoxicity. Reviewing liver enzymes helps in early detection of liver damage. Complete blood counts (Choice A) are not typically affected by azithromycin or acetaminophen. Electrolytes (Choice B) are not directly impacted by these medications. Urinalysis (Choice D) is not specifically indicated for monitoring the side effects of azithromycin and acetaminophen combination therapy.

5. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?

• A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
• B. A serum drug level greater than the MEC broadens the spectrum of the drug.
• C. A serum drug level greater than the MEC helps eradicate bacterial infections.
• D. A serum drug level greater than the MEC increases the therapeutic index.

Correct answer: C

Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.
