Nursing Elites

1. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:

• A. Lack of thirst
• B. Pale skin
• C. Hypertension
• D. Swollen tongue

Correct answer: D

Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.

2. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

3. Which assessment information will be most important for the nurse to report to the healthcare provider about a patient with acute cholecystitis?

• A. The patient's urine is bright yellow
• B. The patient's stools are tan colored
• C. The patient has increased pain after eating
• D. The patient complains of chronic heartburn

Correct answer: B

Rationale: The correct answer is that the patient's stools are tan colored. Tan or grey stools indicate biliary obstruction, which requires rapid intervention to resolve in a patient with acute cholecystitis. This change in stool color is a critical sign that the healthcare provider needs to be informed about promptly. The other choices are less concerning and may be common symptoms in patients with acute cholecystitis, but tan-colored stools specifically indicate a potential serious complication that warrants immediate attention.

4. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

5. One hour after a thoracotomy, a patient complains of incisional pain at a level 7 (based on a 0 to 10 scale) and has decreased left-sided breath sounds. The pleural drainage system has 100 mL of bloody drainage and a large air leak. Which action is best for the nurse to take next?

• A. Milk the chest tube gently to remove any clots.
• B. Clamp the chest tube momentarily to check for the origin of the air leak.
• C. Assist the patient to deep breathe, cough, and use the incentive spirometer.
• D. Set up the patient-controlled analgesia (PCA) and administer the loading dose of morphine.

Correct answer: S

Rationale: In this scenario, the best action is to set up the patient-controlled analgesia (PCA) and administer the loading dose of morphine. The patient's pain level is high, which can hinder deep breathing and coughing. Addressing pain control is a priority to facilitate optimal respiratory function. Milking the chest tube to remove clots is unnecessary as the drainage amount is not alarming in the early postoperative period. Clamping the chest tube to locate the air leak is not recommended as it can lead to tension pneumothorax. Assisting the patient to deep breathe, cough, and use the incentive spirometer is important but should follow adequate pain management to ensure the patient can effectively participate in these activities.
