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 preparing for a dressing change on a full thickness burn to the flank area. The orders include irrigating the wound with each dressing change. To irrigate the wound, what will the nurse use?

• A. Sterile saline
• B. Distilled water
• C. Betadine scrub
• D. Tap water

Correct answer: A

Rationale: When irrigating a wound, especially in the case of a full-thickness burn, it is crucial to use a solution that is gentle and non-irritating to the tissues. Sterile saline is the preferred choice for wound irrigation as it is isotonic and does not cause additional damage to the already compromised tissue. Distilled water lacks the electrolytes present in saline, Betadine scrub is not used for irrigation due to its potential to be cytotoxic, and tap water may introduce contaminants and microorganisms to the wound.

3. The nurse is caring for a client with hyperemesis gravidarum. What is the most likely electrolyte imbalance?

• A. Hypocalcemia
• B. Hypomagnesemia
• C. Hyponatremia
• D. Hypokalemia

Correct answer: D

Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.

4. A healthcare professional is assessing a patient in the rehab unit during shift change. The patient has sustained a TBI 3 weeks ago. Which of the following is the most distinguishing characteristic of a neurological disturbance?

• A. LOC (level of consciousness)
• B. Short-term memory
• C. Babinski sign
• D. Clonus sign

Correct answer: A

Rationale: Level of consciousness (LOC) is the most crucial indicator of impaired neurological function. Changes in LOC can signify various neurological conditions, including traumatic brain injury. Short-term memory, while important, is not the most distinguishing characteristic of neurological disturbances. Babinski and Clonus signs are specific neurological tests that can provide information about upper motor neuron lesions but are not as generalizable as changes in LOC for assessing overall neurological status.

5. The nurse is caring for a client with decreased cardiac output secondary to heart failure with fluid volume overload. The effects of diminished renal perfusion will have which physiologic response?

• A. Diuresis
• B. Increased fluid retention
• C. Elevated bicarbonate level
• D. Paroxysmal idiopathic narcosis

Correct answer: B

Rationale: When there is diminished renal perfusion due to decreased cardiac output, the kidneys receive less blood flow. This leads to a decrease in urine output and an increase in fluid retention, as the kidneys are not able to effectively filter and excrete excess fluid. Elevated bicarbonate level and paroxysmal idiopathic narcosis are not typically associated with diminished renal perfusion in heart failure. Therefore, the correct answer is 'Increased fluid retention.'
