1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A client is receiving teaching from a healthcare provider about reducing the adverse effects of immobility. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will perform ankle and knee exercises every hour - Range of motion (ROM) is needed to prevent contractures.
• B. I will hold my breath when rising from a sitting position.
• C. I will remove my antiembolic stockings while I am in bed.
• D. I will have my partner help me change positions every 4 hours.

Correct answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.

3. How can self-injury be prevented when lifting a bedside cabinet?

• A. Standing close to the cabinet when lifting.
• B. Bending at the waist when lifting.
• C. Twisting while lifting to balance the load.
• D. Lifting with a quick motion.

Correct answer: A

Rationale: The correct way to prevent self-injury when lifting a bedside cabinet is by standing close to the cabinet. By standing close, the individual can maintain better control and balance while lifting, reducing the risk of injury. Bending at the waist when lifting (choice B) can strain the back and lead to injury. Twisting while lifting (choice C) can also cause strain and imbalance. Lifting with a quick motion (choice D) can increase the risk of injury due to lack of control and improper body mechanics.

4. When administering an otic medication to an older adult client, which action should the nurse take to ensure that the medication reaches the inner ear?

• A. Press gently on the tragus of the client's ear
• B. Pack a small piece of cotton deep into the client's ear canal
• C. Move the client's auricle down and back toward their head
• D. Tilt the client's head backward for 5 minutes

Correct answer: A

Rationale: The correct action to ensure that otic medication reaches the inner ear is to press gently on the tragus. The tragus is a small cartilaginous projection in front of the ear canal. Pressing on it helps to straighten the ear canal, allowing the medication to reach the inner ear. Packing cotton or moving the auricle can obstruct the ear canal and prevent proper medication delivery. Tilting the client's head backward is not necessary and may not facilitate the medication reaching the inner ear as effectively as pressing on the tragus.

5. A healthcare provider is assessing a client with a diagnosis of acute pancreatitis. Which laboratory value would be most concerning?

• A. Serum amylase of 200 U/L
• B. Serum lipase of 250 U/L
• C. Blood glucose of 200 mg/dL
• D. Serum calcium of 7.5 mg/dL

Correct answer: D

Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.
