Nursing Elites

1. The nurse notes a serum calcium level of 7.9 mg/dL for a patient who has chronic malnutrition. Which action should the nurse take next?

• A. Monitor ionized calcium level.
• B. Give oral calcium citrate tablets.
• C. Check parathyroid hormone level.
• D. Administer vitamin D supplements.

Correct answer: A

Rationale: This patient with chronic malnutrition is likely to have a low serum albumin level, which will affect the total serum calcium. A more accurate reflection of calcium balance is the ionized calcium level. Most of the calcium in the blood is bound to protein (primarily albumin). Alterations in serum albumin levels affect the interpretation of total calcium levels. Low albumin levels result in a drop in the total calcium level, although the level of ionized calcium is not affected. The nurse should monitor the ionized calcium level to get a clearer picture of the patient's calcium status. Giving oral calcium citrate tablets, checking parathyroid hormone level, or administering vitamin D supplements may be necessary based on the ionized calcium results, but they are not the immediate next step in assessment and management.

2. At 01:00 on a male client's second postoperative night, the client states he is unable to sleep and plans to read until feeling sleepy. What action should the nurse implement?

• A. Leave the room and close the door to the client's room
• B. Assess the appearance of the client's surgical dressing
• C. Bring the client a prescribed PRN sedative-hypnotic
• D. Discuss symptoms of sleep deprivation with the client

Correct answer: A

Rationale: The client has a plan to read until feeling sleepy, indicating an intention to sleep. Therefore, offering a PRN sedative-hypnotic (C) is unnecessary, especially since it is a stronger sleep aid. Option (D) is not needed as the client already has a plan to address his sleeplessness. Assessing the surgical dressing (B) is not relevant to the client's immediate need for sleep. Leaving the room and closing the door (A) is the appropriate action to provide a conducive environment for the client to rest.

3. After receiving change-of-shift report, which patient should the nurse assess first?

• A. Patient with a serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping
• B. Patient with a serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water
• C. Patient with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes
• D. Patient with a serum phosphorus level of 4.5 mg/dL who has multiple soft tissue calcium-phosphate precipitates

Correct answer: C

Rationale: The correct answer is patient C with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes. The low magnesium level and neuromuscular irritability suggest that the patient may be at risk for seizures, which are life-threatening. Assessing and addressing this patient's condition promptly is crucial to prevent complications. Patients A, B, and D have mild electrolyte disturbances or symptoms that require attention, but they are not at immediate risk for life-threatening complications like seizures, unlike patient C.

4. The nurse assesses a client who has a nasal cannula delivering oxygen at 2 L/min. To assess for skin damage related to the cannula, which areas should the nurse observe? (Select all that apply).

• A. Tops of the ears
• B. Bridge of the nose
• C. Around the nostrils
• D. Over the cheeks

Correct answer: C

Rationale: The correct answer is C: 'Around the nostrils.' Constant pressure from the tubing may create skin damage to the areas of skin and bony prominences the nasal cannula will be resting on, including around the nostrils. Choice A, 'Tops of the ears,' is incorrect as the cannula does not rest on the ears. Choice B, 'Bridge of the nose,' is incorrect because the cannula typically rests under the nose. Choice D, 'Over the cheeks,' is also incorrect as the cannula does not typically rest on the cheeks.

5. The long-term care nurse is evaluating the effectiveness of protein supplements for an older resident who has a low serum total protein level. Which assessment finding indicates that the patient’s condition has improved?

• A. Hematocrit 28%
• B. Absence of skin tenting
• C. Decreased peripheral edema
• D. Blood pressure 110/72 mm Hg

Correct answer: C

Rationale: The decrease in peripheral edema indicates an improvement in the patient’s protein status. Edema is caused by low oncotic pressure in individuals with low serum protein levels. Good skin turgor is an indicator of fluid balance, not protein status. A low hematocrit could be caused by poor protein intake. Blood pressure does not provide a useful clinical tool for monitoring protein status.
