A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?
- A. Serum creatine kinase (CK)
- B. Serum troponin
- C. Serum myoglobin
- D. C-reactive protein (CRP)
Correct Answer: B
Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

A client with a history of hypertension is admitted with shortness of breath and chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Pulmonary function tests (PFTs)
- D. Arterial blood gases (ABGs)
Correct Answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia in a client presenting with shortness of breath and chest pain. This test helps in evaluating the electrical activity of the heart and can identify signs of myocardial infarction or other cardiac issues. Choice B, Chest X-ray, may be ordered after the ECG to assess for pulmonary conditions like pneumonia or effusions. Choice C, Pulmonary function tests (PFTs), are used to evaluate lung function and are not the primary diagnostic tests for a client with symptoms of cardiac origin. Choice D, Arterial blood gases (ABGs), may provide information about oxygenation but are not the initial test indicated for a client with suspected cardiac issues.
A nurse is teaching a client with type 2 diabetes about the importance of foot care. Which statement by the client indicates a need for further teaching?
- A. I should check my feet every day for cuts or blisters.
- B. I need to moisturize my feet daily, especially between my toes.
- C. I should wear comfortable shoes that fit well.
- D. I should avoid walking barefoot, even indoors.
Correct Answer: B
Rationale: The correct answer is B. Moisturizing between the toes can create a moist environment that fosters fungal infections. Checking the feet daily for cuts or blisters (choice A) is correct in diabetes management to prevent complications. Wearing comfortable shoes that fit well (choice C) and avoiding walking barefoot (choice D) are also essential in preventing foot ulcers and injuries in diabetic patients.
A client with newly diagnosed hypertension is being taught about lifestyle modifications by a nurse. Which client statement indicates a need for further teaching?
- A. 'I will reduce my salt intake to help manage my blood pressure.'
- B. 'I will start exercising regularly to help control my blood pressure.'
- C. 'I will avoid drinking alcohol to help manage my blood pressure.'
- D. 'I will limit my caffeine intake to help control my blood pressure.'
Correct Answer: D
Rationale: The correct answer is D. Limiting caffeine intake is a positive lifestyle modification for managing hypertension. The statement indicates that the client understands the importance of reducing caffeine intake. Choices A, B, and C all reflect appropriate lifestyle modifications for managing hypertension, indicating good understanding by the client.
A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Blood urea nitrogen (BUN) of 40 mg/dl
- C. Serum potassium of 6.0 mEq/L
- D. Serum creatinine of 2.5 mg/dl
Correct Answer: C
Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.
A male client is having abdominal pain after a left femoral angioplasty and stent, and is asking for additional pain medication for right lower quadrant pain (9/10). Two hours ago, he received hydrocodone/acetaminophen 7.5/7.50 mg. His vital signs are elevated from the previous hour: temperature 97.8 F, heart rate 102 beats per minute, respiration 20 breaths per minute. His abdomen is swollen, the groin access site is tender, peripheral pulses are present, but the left leg is larger than the right. Preoperatively, clopidogrel was prescribed for a history of previous peripheral stents. Another nurse is holding manual pressure on the femoral arterial access site which may be leaking into the abdomen. What data is needed to make this report complete?
- A. Client's lungs are clear bilaterally, and oxygen saturation is 97%.
- B. The surgeon needs to see the client immediately to evaluate the situation.
- C. Left peripheral pulses were present only by Doppler pre-procedure.
- D. Client's history includes multiple back surgeries and chronic pain.
Correct Answer: B
Rationale: The correct answer is B. Immediate evaluation by the surgeon is necessary due to the possibility of an internal hemorrhage, which is a life-threatening condition. Choice A is incorrect as lung status and oxygen saturation are not the priority in this situation. Choice C is not relevant to the current urgent issue. Choice D, while providing additional history, is not pertinent to the immediate concern of a potential internal hemorrhage post angioplasty and stent placement.
