Nursing Elites

1. A client with a cold is taking the antitussive benzonatate (Tessalon). Which assessment data indicates to the nurse that the medication is effective?

• A. Reports reduced nasal discharge.
• B. Denies having coughing spells.
• C. Able to sleep through the night.
• D. Expectorating bronchial secretions.

Correct answer: B

Rationale: The correct answer is B. Denying having coughing spells indicates the effectiveness of benzonatate, an antitussive that suppresses coughing. The goal of antitussive medications like benzonatate is to reduce or eliminate coughing, so the absence of coughing spells signifies the drug's efficacy. The other options do not directly reflect the medication's intended effect and are not specific indicators of benzonatate's effectiveness.

2. A 46-year-old man with a history of cirrhosis is brought in by his wife because he has been acting strangely. On examination, he is disoriented, ataxic, and has slurred speech. He is also hyperreflexic. His white blood cell count is normal. His hematocrit is 34%. Coagulation times are elevated. His ammonia level is normal. Which of the following statements regarding his management is correct?

• A. He should be treated with a low-protein diet and lactulose
• B. Lorazepam is not the drug of choice to control his behavior
• C. He should not be placed on gentamicin prophylactically to prevent the development of peritonitis
• D. If the patient complains of pain, acetaminophen should be avoided and nonsteroidal anti-inflammatory agents should be used

Correct answer: A

Rationale: This patient presents with symptoms consistent with hepatic encephalopathy. Despite having a normal ammonia level, he should be treated with lactulose and a low-protein diet as recommended for stage 2 hepatic encephalopathy. The normal ammonia level does not exclude the diagnosis, as it lacks sensitivity and specificity. Medications like lorazepam, gentamicin, and NSAIDs should be avoided due to their potential adverse effects in patients with liver disease. Acetaminophen should also be avoided in such patients.

3. When assessing a client with suspected meningitis, which finding is indicative of meningeal irritation?

• A. Brudzinski's sign
• B. Positive Babinski reflex
• C. Kernig's sign
• D. Both A and C

Correct answer: D

Rationale: Both Brudzinski's sign and Kernig's sign are classic signs of meningeal irritation, commonly associated with meningitis. Brudzinski's sign is positive when flexing the neck causes involuntary flexion of the hips and knees due to irritation of the meninges. Kernig's sign is positive when there is pain and resistance with knee extension after hip flexion, indicating meningeal irritation or inflammation. The Babinski reflex, mentioned in choice B, is a test used to assess upper motor neuron damage and is not specific to meningitis. Therefore, choices A and C are the correct options as they are indicative of meningeal irritation in a suspected case of meningitis.

4. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

5. When assessing a client with a chest tube connected to suction, which observation indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation in the water seal chamber.
• D. Steady bubbling in the suction control chamber.

Correct answer: D

Rationale: Steady bubbling in the suction control chamber is the correct observation that indicates the chest tube is functioning properly. This steady bubbling signifies that the suction is actively maintaining the desired pressure level within the system, ensuring proper drainage and lung re-expansion. Continuous bubbling in the water seal chamber, intermittent bubbling in the suction control chamber, or no fluctuation in the water seal chamber are not indicative of optimal chest tube function and may require further assessment or intervention.
