Nursing Elites

1. A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO2 88 mm Hg, PaCO2 37 mm Hg, and HCO3 16 mEq/L. How should the nurse interpret these results?

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

Correct answer: A

Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.

2. The nurse observes an unlicensed assistive personnel (UAP) who is providing a total bed bath for a confused and lethargic client. The UAP is soaking the client's foot in a basin of warm water placed on the bed. What action should the nurse take?

• A. Remove the basin of water from the client's bed immediately
• B. Remind the UAP to dry between the client's toes completely
• C. Advise the UAP that this procedure is damaging to the skin
• D. Add skin cream to the basin of water while the foot is soaking

Correct answer: B

Rationale: Choice (B) is the correct action for the nurse to take in this situation. Ensuring that the UAP dries between the client's toes completely is crucial to prevent skin breakdown due to excessive moisture. While keeping the client's feet clean is important, maintaining dryness is paramount for skin integrity. Choices (A), (C), and (D) are incorrect: (A) removing the basin of water immediately may disrupt the care process without addressing the root issue, (C) advising the UAP that the procedure is damaging to the skin is not as immediate or specific to the observed problem, and (D) adding skin cream to the water may not address the need for drying the client's toes thoroughly.

3. The nurse is caring for a patient with a massive burn injury and possible hypovolemia. Which assessment data will be of most concern to the nurse?

• A. Blood pressure is 90/40 mm Hg.
• B. Urine output is 30 mL over the last hour.
• C. Oral fluid intake is 100 mL over the last 8 hours.
• D. There is prolonged skin tenting over the sternum.

Correct answer: A

Rationale: The correct answer is A: "Blood pressure is 90/40 mm Hg." A low blood pressure reading of 90/40 mm Hg indicates that the patient may be developing hypovolemic shock due to intravascular fluid loss from the burn injury. This finding is of utmost concern as it suggests systemic hypoperfusion, requiring immediate intervention to prevent complications. Choices B, C, and D also indicate signs of dehydration and the need to increase fluid intake; however, they are not as urgent as addressing the hypotension and potential shock presented in choice A.

4. The home health nurse cares for an alert and oriented older adult patient with a history of dehydration. Which instructions should the nurse give to this patient related to fluid intake?

• A. Increase fluids if your mouth feels dry.
• B. More fluids are needed if you feel thirsty.
• C. Drink more fluids in the late evening hours.
• D. If you feel lethargic or confused, you need more to drink.

Correct answer: A

Rationale: The correct answer is A. An alert, older patient can self-assess for signs of dehydration like dry mouth. This instruction is appropriate as it encourages the patient to respond to early signs of dehydration. Choice B is incorrect because the thirst mechanism decreases with age and feeling thirsty may not accurately indicate the need for fluids. Choice C is incorrect as many older patients prefer to limit evening fluid intake to enhance sleep quality. Choice D is incorrect because an older adult who is lethargic or confused may not be able to accurately assess their need for fluids.

5. When assessing a male client, the nurse finds that he is fatigued, and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D, Hypokalemia. Generalized weakness, muscle weakness, leg cramps, and cardiac dysrhythmias are manifestations of hypokalemia. Checking the potassium level is essential in this case. Hypocalcemia typically presents with facial muscle spasms, not the symptoms mentioned. Hypermagnesemia does not typically cause the symptoms described. It's important to note that orange juice is high in potassium and would be advisable to drink if the patient was hypokalemic. Loose stools are more commonly associated with hyperkalemia, not hypokalemia.
