Nursing Elites

1. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?

• A. Ca
• B. K
• C. Na
• D. Cl

Correct answer: B

Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.

2. A 15-year-old high school wrestler has been taking diuretics to lose weight to compete in a lower weight class. Which of the following medical tests is most likely to be given?

• A. Lab values of Potassium and Sodium
• B. Lab values of Glucose and Hemoglobin
• C. ECG
• D. CT scan

Correct answer: A

Rationale: Diuretics can disrupt the sodium and potassium balance, potentially leading to cardiac complications. Monitoring the lab values of potassium and sodium is crucial to assess electrolyte imbalances due to diuretic use. Testing glucose and hemoglobin levels is not directly related to diuretic use in this context. An ECG would be indicated if there were signs or symptoms of cardiac abnormalities, but it is not the primary test to monitor the effects of diuretics. A CT scan is not typically used to assess electrolyte imbalances caused by diuretics.

3. The nurse is caring for a client complaining of intense headaches with increasing pain for the past one month. An MRI is ordered. In reviewing the client's information, which piece of information is of concern?

• A. Allergy to shellfish
• B. Has a cardiac pacemaker
• C. A diabetic
• D. No IV access

Correct answer: B

Rationale: The correct answer is 'Has a cardiac pacemaker.' If a client with a cardiac pacemaker undergoes an MRI, the magnetic field can interfere with the pacemaker's function, leading to serious complications or even death. It is crucial to ensure that the pacemaker is compatible with MRI imaging or to consider alternative imaging modalities. The other choices, such as 'Allergy to shellfish,' 'A diabetic,' and 'No IV access,' are not direct contraindications for an MRI scan and do not pose the same level of risk as having a cardiac pacemaker.

4. While assessing a patient who has undergone a recent CABG, the nurse notices a mole with irregular edges and a bluish color. What should the nurse do next?

• A. Recommend a dermatological consult to the physician.
• B. Note the location of the mole and contact the physician via telephone.
• C. Note the location of the mole and follow-up with the attending physician through the medical record and a phone call.
• D. Remove the mole with a sharp debridement technique, following approval from the charge nurse.

Correct answer: C

Rationale: In this scenario, the nurse should note the location of the mole and follow up with the attending physician through the medical record and a phone call. This action is appropriate because a mole with irregular edges and a bluish color raises concern for melanoma, a type of skin cancer. Recommending a dermatological consult (Choice A) might delay the evaluation and management of the mole. Contacting the physician via telephone (Choice B) may not provide a documented record of the observation. Removing the mole without proper evaluation (Choice D) could be dangerous and is not within the nurse's scope of practice.

5. A client is 36 hours post-op a TKR surgery. 270 cc of sero-sanguinous fluid accumulates in the surgical drains. What action should the nurse take?

• A. Notify the doctor
• B. Empty the drain
• C. Do nothing
• D. Remove the drain

Correct answer: A

Rationale: The correct action for the nurse to take in this situation is to notify the doctor. Significant sero-sanguinous drainage after TKR surgery could indicate a potential issue such as infection or bleeding. The physician needs to be informed promptly to assess the situation and determine the appropriate course of action. Emptying the drain, doing nothing, or removing the drain without consulting the physician could lead to complications going unnoticed or untreated. It is crucial to involve the physician in decision-making to ensure the best outcomes for the client.
