Adult Health 2 Final Exam

Correct Answer: D

Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.

Correct Answer: B

Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.

Correct Answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

Correct Answer: B

Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.

Correct Answer: D

Rationale: A glucose level of 50 mg/dL is indicative of hypoglycemia, which requires immediate intervention to prevent further complications. Hypoglycemia can lead to serious consequences such as altered mental status, seizures, and even coma if not promptly addressed. The other options do not present immediate life-threatening conditions that require urgent intervention. Shortness of breath with a hemoglobin of 8 grams may indicate anemia but does not require immediate intervention. Bleeding from a finger stick with a prothrombin time of 30 seconds may suggest clotting issues, which are important but not as immediately critical as hypoglycemia. Being febrile with an elevated WBC count could indicate infection, which is concerning but not as urgently critical as hypoglycemia.
