Nursing Elites

1. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.

2. 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.

3. A patient has been prescribed Tegretol for the first time. Which of the following side effects is not associated with Tegretol?

• A. Sore throat
• B. Vertigo
• C. Fever
• D. Shortness of breath

Correct answer: D

Rationale: The correct answer is 'Shortness of breath.' Side effects commonly associated with Tegretol include sore throat, vertigo, and fever. Shortness of breath is not a typical side effect of Tegretol use. Sore throat, vertigo, and fever are known side effects of Tegretol, while shortness of breath is not typically linked to its use.

4. When administering intravenous electrolyte solution, what precaution should the nurse take?

• A. Infuse hypertonic solutions cautiously.
• B. Mix no more than 60 mEq of potassium per liter of fluid.
• C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
• D. Monitor the client's digitalis dosage for adjustments due to IV calcium.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer. Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects. Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia. Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.

5. Which of the following is the drug of choice to decrease uric acid levels?

• A. prednisone (Colisone)
• B. allopurinol (Zyloprim)
• C. indomethacin (Indocin)
• D. hydrochlorothiazide (HydroDiuril)

Correct answer: B

Rationale: Allopurinol is the correct drug to decrease uric acid levels as it is used to treat gout by reducing uric acid formation. Prednisone is a corticosteroid that decreases inflammation, not uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, not specifically used to reduce uric acid levels. Hydrochlorothiazide is a thiazide diuretic primarily used for treating hypertension and edema, not for reducing uric acid levels.
