Nursing Elites

1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?

• A. Serum potassium
• B. Serum calcium
• C. Serum albumin
• D. Serum sodium

Correct answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

2. While administering a cleansing enema, the client reports abdominal cramping. Which of the following actions should the nurse take?

• A. Have the client hold their breath briefly and bear down.
• B. Clamp the enema tubing.
• C. Remind the client that cramping is common at this time.
• D. Raise the level of the enema fluid container.

Correct answer: C

Rationale: When a client reports abdominal cramping during a cleansing enema, it is important for the nurse to reassure the client that cramping is a common side effect. This reassurance helps the client understand that the cramping is normal and may subside once the enema is completed. Instructing the client to hold their breath and bear down (Choice A) is not appropriate and may cause discomfort. Clamping the enema tubing (Choice B) is unnecessary and could lead to complications. Raising the level of the enema fluid container (Choice D) does not address the client's discomfort due to cramping. Therefore, the most suitable action is to provide reassurance to the client about the common occurrence of cramping during the enema.

3. A client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?

• A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
• B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
• C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
• D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”

Correct answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

4. A healthcare professional is reviewing a client's medication prescription, which reads, 'digoxin 0.25 by mouth every day.' Which of the following components of the prescription should the healthcare professional question?

• A. the medication
• B. the route
• C. the dose
• D. the frequency

Correct answer: C

Rationale: The healthcare professional should question the dose indicated in the prescription. In this case, '0.25' is incomplete without a unit of measurement, such as mg (milligrams). Without a specified unit, the dose lacks the necessary information for accurate administration. Choices A, B, and D are not incorrect components to question in medication prescriptions; however, in this scenario, the incompleteness of the dose is the most critical concern that needs clarification to ensure safe and effective medication administration.

5. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.
