Question 1 of 9

Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:

Correct Answer: A

Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.

Question 2 of 9

The LPN is preparing to ambulate a client post total knee replacement. Which of the following actions should the nurse perform prior to ambulating the client?

Correct Answer: A

Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.

Question 3 of 9

A female client complains to the nurse at the health department that she has fatigue, shortness of breath, and lightheadedness. Her history reveals no significant medical problems. She states that she is always on a fad diet without any vitamin supplements. Which tests should the nurse expect the client to have first?

Correct Answer: B

Rationale: The correct answer is to perform a complete blood count, including hematocrit and hemoglobin, as the initial tests to assess the client's symptoms related to fatigue, shortness of breath, and lightheadedness. These symptoms can be indicative of anemia, which can be caused by nutritional deficiencies due to fad dieting without vitamin supplements. Peptic ulcer studies, genetic testing, and hemoglobin electrophoresis are not the most appropriate initial tests for the client's presenting symptoms and history. Peptic ulcer studies are not relevant to the client's symptoms. Genetic testing is not indicated based on the client's presentation and history. Hemoglobin electrophoresis is used to diagnose specific types of anemia and is not the first-line test in this scenario. Further testing decisions should be based on the results of the initial tests, the client's history, and other relevant factors.

Question 4 of 9

What are the major electrolytes in the extracellular fluid?

Correct Answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

Question 5 of 9

The client seeks advice from the nurse regarding issues with flatus due to colostomy. Which food should the nurse recommend?

Correct Answer: D

Rationale: The correct answer is yogurt. Yogurt can help reduce gas formation in clients with a colostomy. High-fiber foods like bran can stimulate peristalsis and increase flatulence, which is not helpful in this situation. Cruciferous vegetables, such as cabbage, broccoli, and kale, and beans tend to increase gas formation. Carbonated beverages, along with smoking, chewing gum, and drinking fluids with a straw, can also increase gas formation. Therefore, the nurse should recommend yogurt to help alleviate the client's issues with flatus.

Question 6 of 9

The nurse is caring for a client following an appendectomy. The client reports nausea and complains of surgical site pain at a 6 on a 0 to 10 scale. The client's employer is present in the room and states he is paying for the insurance and wants to know what pain medication has been prescribed by the physician. Which of the following is the appropriate nurse response?

Correct Answer: C

Rationale: The appropriate nurse response is to explain to the employer that private information cannot be released and ask the employer to step out while conducting the assessment. This approach respects the client's privacy while still acknowledging the employer. The employer's payment for insurance does not grant rights to confidential information. Sharing information without permission violates the client's right to privacy under HIPAA. Option A is incorrect as it compromises the client's confidentiality by sharing private medical information. Option B is inappropriate and unprofessional as it does not address the situation respectfully. Option D is incorrect as it does not prioritize the client's immediate needs and assumes the client's consent without proper communication.

Question 7 of 9

The nurse is assessing the newborn's respirations. Which of these findings would indicate a need for follow-up and further intervention?

Correct Answer: D

Rationale: The ideal respiratory rate in a newborn is 30-60 breaths per minute. A respiratory rate of 70 breaths per minute indicates tachypnea and may require intervention. Therefore, a rate of 70 breaths per minute would necessitate follow-up and further intervention. Irregular, abdominal, and shallow respirations are common in newborns and may not necessarily indicate the need for immediate follow-up or intervention.

Question 8 of 9

A client was involved in a motor vehicle accident in which the seat belt was not worn. The client is exhibiting crepitus, decreased breath sounds on the left, complains of shortness of breath, and has a respiratory rate of 34/min. Which of the following assessment findings should concern the nurse the most?

Correct Answer: C

Rationale: The correct answer is 'trachea deviating to the right.' A mediastinal shift is indicative of a tension pneumothorax, which is a dangerous complication seen in trauma patients with symptoms like crepitus, decreased breath sounds, shortness of breath, and tachypnea. Assessing for acute traumatic injuries is crucial in this context. Choice A, a temperature of 102°F and a productive cough, is common in pneumonia cases and not as concerning as a mediastinal shift. Choice B, ABGs with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg, shows values within normal limits and does not suggest a tension pneumothorax. Choice D, a barrel-chested appearance, is typical of COPD and not directly related to the acute traumatic injury described. A tension pneumothorax is a medical emergency where air cannot escape the pleural cavity, leading to lung collapse and a mediastinal shift to the unaffected side with a downward displacement of the diaphragm.

Question 9 of 9

The nurse is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?

Correct Answer: B

Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.
