1. Which of the following is a key symptom of myocardial infarction (MI)?

• A. Chest pain.
• B. Shortness of breath.
• C. Nausea.
• D. Fatigue.

Correct answer: A

Rationale: The correct answer is A: Chest pain. Chest pain is a hallmark symptom of myocardial infarction (MI) due to inadequate blood flow to the heart muscle. This pain can be severe, crushing, or squeezing, and may radiate to the left arm, jaw, or back. Shortness of breath (choice B), nausea (choice C), and fatigue (choice D) can accompany MI but are not as specific or characteristic as chest pain in diagnosing this condition. Therefore, chest pain is the primary symptom to recognize for suspected MI.

2. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

3. A nurse cares for a client with urinary incontinence. The client states, “I am so embarrassed. My bladder leaks like a young child’s bladder.” How should the nurse respond?

• A. I understand how you feel. I would be mortified.
• B. Incontinence pads will minimize leaks in public.
• C. I can teach you strategies to help control your incontinence.
• D. More women experience incontinence than you might think.

Correct answer: C

Rationale: The nurse should accept and acknowledge the client’s concerns, and assist the client to learn techniques that will allow control of urinary incontinence. The nurse should not diminish the client’s concerns with the use of pads or stating statistics about the occurrence of incontinence.

4. A nurse is assessing the chest tube drainage system of a postoperative client who has undergone a right upper lobectomy. The closed drainage system contains 300 mL of bloody drainage, and the nurse notes intermittent bubbling in the water seal chamber. One hour after the initial assessment, the nurse notes that the bubbling in the water seal chamber is now constant, and the client appears dyspneic. On the basis of these findings, the nurse should first assess:

• A. The client’s vital signs
• B. The amount of drainage
• C. The client’s lung sounds
• D. The chest tube connections

Correct answer: D

Rationale: The client’s dyspnea is most likely related to an air leak caused by a loose connection in the chest tube system. Checking the chest tube connections should be the initial action because correcting an air leak can quickly resolve the client's symptoms. If a leak is found and corrected, the dyspnea should improve. Assessing the client’s vital signs (Option A) is important, but addressing the potential cause of dyspnea takes precedence. Monitoring the amount of drainage (Option B) is necessary for assessing the client's overall condition, but in this case, the dyspnea is likely due to an air leak. Checking the client’s lung sounds (Option C) is essential for respiratory assessment, but addressing the air leak should be the immediate priority to ensure adequate lung expansion and oxygenation.

5. A client who had a C-5 spinal cord injury 2 years ago is admitted to the emergency department with the diagnosis of autonomic dysreflexia secondary to a full bladder. Which assessment finding should the nurse expect this client to exhibit?

• A. Complaints of chest pain and shortness of breath
• B. Hypotension and venous pooling in the extremities
• C. Profuse diaphoresis and severe, pounding headache
• D. Pain and burning sensation upon urination and hematuria

Correct answer: C

Rationale: Autonomic dysreflexia is a life-threatening condition commonly seen in clients with spinal cord injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure due to a noxious stimulus below the level of injury, often a distended bladder. The exaggerated sympathetic response leads to vasoconstriction, resulting in symptoms such as profuse diaphoresis (sweating) and a severe, pounding headache. These symptoms are the body's attempt to lower blood pressure. Complaints of chest pain and shortness of breath (Choice A) are not typical findings in autonomic dysreflexia. Hypotension and venous pooling (Choice B) are opposite manifestations of autonomic dysreflexia, which is characterized by hypertension. Pain and burning sensation upon urination and hematuria (Choice D) are indicative of a urinary tract infection and not specific to autonomic dysreflexia.
