Nursing Elites

1. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?

• A. Muscle cramps.
• B. Hypertension.
• C. Bradycardia.
• D. Tachycardia.

Correct answer: D

Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.

2. A 70-kg adult with chronic renal failure is on a 40-g protein diet. The client has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would give the nurse the most concern?

• A. Albumin level of 2.5 g/dL
• B. Phosphorus level of 5 mg/dL
• C. Sodium level of 135 mmol/L
• D. Potassium level of 5.5 mmol/L

Correct answer: A

Rationale: In chronic renal failure, a protein-restricted diet is crucial to prevent the buildup of waste products. A low albumin level (<3.5 g/dL) indicates inadequate protein intake, raising concern as it may lead to malnutrition and tissue breakdown. Phosphorus, sodium, and potassium levels are not directly impacted by protein intake. Phosphorus levels may elevate in renal failure, but at 5 mg/dL, it is within normal range. Sodium and potassium levels are also within normal limits and not influenced by protein restriction.

3. The adult client admitted to the post-anesthesia care unit (PACU) following abdominal surgery has a tympanic temperature of 94.6°F (34.8°C), a pulse rate of 88 beats/minute, a respiratory rate of 14 breaths/minute, and a blood pressure of 94/64 mmHg. Which action should the nurse implement?

• A. Take the client's temperature using another method.
• B. Raise the head of the bed to 60 to 90 degrees.
• C. Ask the client to cough and deep breathe.
• D. Check the blood pressure every five minutes for one hour.

Correct answer: A

Rationale: Taking the client's temperature using another method is the most appropriate action in this situation. A tympanic temperature of 94.6°F (34.8°C) is abnormally low and may not reflect the true core body temperature accurately. By using an alternative method, such as oral or rectal temperature measurement, the nurse can obtain a more reliable temperature reading. Raising the head of the bed (Choice B) is not directly related to addressing the low temperature. Asking the client to cough and deep breathe (Choice C) may be beneficial for respiratory function but does not address the temperature concern. Checking the blood pressure every five minutes for one hour (Choice D) is not the priority when the initial focus should be on accurate temperature assessment.

4. The healthcare provider provides dietary instructions about iron-rich food to a client with iron deficiency anemia. Which food selection made by the client indicates a need for additional instructions?

• A. Liver
• B. Kidney beans
• C. Oranges
• D. Leafy green vegetables

Correct answer: C

Rationale: Oranges are not a good source of iron, so selecting oranges indicates a need for additional instructions. Oranges are high in vitamin C, which can enhance iron absorption from other sources, but they are not rich in iron themselves. Liver, kidney beans, and leafy green vegetables are good sources of iron and would be beneficial for a client with iron deficiency anemia. Therefore, the correct answer is C.

5. A nurse reviews laboratory results for a client with glomerulonephritis. The client’s glomerular filtration rate (GFR) is 40 mL/min as measured by a 24-hour creatinine clearance. How should the nurse interpret this finding? (Select all that apply.)

• A. Excessive GFR
• B. Reduced GFR
• C. Fluid retention and risks for hypertension
• D. Pulmonary edema

Correct answer: B

Rationale: A GFR of 40 mL/min indicates a reduced glomerular filtration rate. In a healthy adult, the normal GFR ranges between 100 and 120 mL/min. A GFR of 40 mL/min signifies a significant reduction, leading to fluid retention and risks for hypertension and pulmonary edema due to excess vascular fluid. Choices A, C, and D are incorrect. Choice A is incorrect as a GFR of 40 mL/min is not excessive but rather reduced. Choices C and D do not directly address the interpretation of GFR but instead describe potential consequences of a reduced GFR.
