Nursing Elites

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. When performing nasotracheal suctioning for a client with a respiratory infection, what technique should the nurse use?

• A. Apply intermittent suction when withdrawing the catheter
• B. Suction continuously while inserting the catheter
• C. Suction intermittently while inserting the catheter
• D. Use a Yankauer suction device

Correct answer: A

Rationale: When performing nasotracheal suctioning for a client with a respiratory infection, the nurse should apply intermittent suction when withdrawing the catheter. This technique helps minimize mucosal damage and is considered best practice. Choice B, suctioning continuously while inserting the catheter, is incorrect as continuous suctioning can cause trauma to the airway. Choice C, suctioning intermittently while inserting the catheter, is also incorrect as it can increase the risk of hypoxia and mucosal damage. Choice D, using a Yankauer suction device, is not appropriate for nasotracheal suctioning as it is typically used for oral suctioning. Therefore, the correct technique is to apply intermittent suction when withdrawing the catheter to ensure effective and safe suctioning.

3. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 0.5 mL
• B. 1 mL
• C. 1.5 mL
• D. 2 mL

Correct answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

4. An older adult client has been hospitalized on bed rest for 1 week. The client reports elbow pain. Which of the following is an appropriate initial action for the nurse caring for this client to take?

• A. Examine the elbow
• B. Administer pain medication
• C. Apply a warm compress to the elbow
• D. Assess the client’s range of motion

Correct answer: A

Rationale: The appropriate initial action for the nurse is to examine the elbow. This step is crucial to assess the site of pain, identify any visible signs of injury or inflammation, and determine the cause of the discomfort. Administering pain medication (Choice B) should come after a thorough assessment. Applying a warm compress (Choice C) might provide temporary relief but does not address the underlying cause. Assessing the client’s range of motion (Choice D) is important but would come after the initial examination to further evaluate the elbow joint.

5. When is a depressed client at highest risk for attempting suicide?

• A. Immediately after admission, during one-to-one observation
• B. 7 to 14 days after initiation of antidepressant medication and psychotherapy
• C. Following an angry outburst with family
• D. When the client is removed from the security room

Correct answer: B

Rationale: Depressed clients are at the highest risk of attempting suicide 7 to 14 days after starting antidepressant medication and psychotherapy. During this time, they may start to regain energy but still feel hopeless, which can increase the risk of suicidal ideation and behavior. Choices A, C, and D are incorrect because immediate post-admission, after an angry outburst with family, or when removed from a security room are not specific periods known to be associated with the highest risk of suicide in depressed clients.
