Nursing Elites

1. A twenty-one-year-old man suffered a concussion, and the MD ordered an MRI. The patient asks, 'Will they allow me to sit up during the MRI?' The correct response by the nurse should be:

• A. "I will have to talk to the doctor about letting you sit upright during the test."?
• B. "You will be positioned in the reverse Trendelenburg position to maximize the view of the brain."?
• C. "The radiologist will let you know."?
• D. "You will have to lie down on your back during the test."?

Correct answer: D

Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain. Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test. Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans. Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.

2. The nurse is caring for a client with epilepsy who is being treated with carbamazepine (Tegretol). Which laboratory value might indicate a serious side effect of this drug?

• A. Uric acid of 5 mg/dL
• B. Hematocrit of 33%
• C. WBC 2,000 per cubic millimeter
• D. Platelets 150,000 per cubic millimeter

Correct answer: C

Rationale: Carbamazepine (Tegretol) can suppress the bone marrow, leading to a decrease in the white blood cell count. A laboratory value of WBC 2,000 per cubic millimeter indicates a serious side effect of the drug. Choices A and D are within normal limits, while choice B is at the lower limit of normal. Therefore, choices A, B, and D are incorrect.

3. A 10-month-old child is brought to the Emergency Department because he is difficult to awaken. The nurse notes bruises on both upper arms. These findings are most consistent with

• A. wearing clothing that is too small for the child
• B. the child being shaken
• C. falling while learning to walk
• D. parents trying to awaken the child

Correct answer: B

Rationale: The correct answer is 'the child being shaken.' Children who are shaken are frequently grasped by both upper arms, leading to bruises in that area. The presentation of a difficult-to-awaken child with bruises on the upper arms is highly concerning for non-accidental trauma, such as abusive shaking. Symptoms of brain injury associated with shaking include a decreased level of consciousness. Choices A, C, and D are less likely because the combination of a child being difficult to awaken and bruises on both upper arms is highly suggestive of non-accidental trauma rather than benign causes like ill-fitting clothing, falling while learning to walk, or parents trying to awaken the child.

4. The licensed practical nurse is observing a graduate nurse as she assesses the central venous pressure. Which observation would indicate that the graduate needs further teaching?

• A. The graduate places the client in a supine position to read the manometer.
• B. The graduate turns the stop-cock to the off position from the IV fluid to the client.
• C. The graduate instructs the client to perform the Valsalva maneuver during the CVP reading.
• D. The graduate notes the level at the top of the meniscus.

Correct answer: C

Rationale: The correct answer is C because the client should breathe normally during a central venous pressure monitor reading. Placing the client in a supine position (Choice A) is correct if the client can tolerate it. Turning the stop-cock off (Choice B) and noting the level at the top of the meniscus (Choice D) are also correct actions during CVP monitoring. Instructing the client to perform the Valsalva maneuver is incorrect as it can artificially alter the CVP reading, indicating a need for further teaching.

5. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.
