Nursing Elites

1. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

2. A client with a history of peptic ulcer disease (PUD) is admitted after vomiting bright red blood several times over the course of 2 hours. In reviewing the laboratory results, the nurse finds the client's hemoglobin is 12 g/dL (120g/L) and the hematocrit is 35% (0.35). Which action should the nurse prepare to take?

• A. Continue monitoring for blood loss
• B. Administer 1,000 mL (1L) of normal saline
• C. Transfuse 2 units of platelets
• D. Prepare the client for emergency surgery

Correct answer: D

Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.

3. 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.

4. The nurse instructs the unlicensed nursing personnel (UAP) on how to provide oral hygiene for clients who cannot perform this task for themselves. Which of the following techniques should the nurse tell the UAP to incorporate into the client's daily care?

• A. Assess the oral cavity each time mouth care is given and record observations.
• B. Use a soft toothbrush to brush the client's teeth after each meal.
• C. Swab the client's tongue, gums, and lips with a soft foam applicator every 2 hours.
• D. Rinse the client's mouth with mouthwash several times a day.

Correct answer: B

Rationale: The correct technique to incorporate into the client's daily care for oral hygiene is to use a soft toothbrush to brush the client's teeth after each meal. This helps in maintaining oral hygiene for clients who cannot perform this task themselves. Choice A is incorrect because assessing the oral cavity each time mouth care is given is important but not the technique to incorporate into daily care. Choice C is incorrect as swabbing the tongue, gums, and lips every 2 hours may not be necessary for daily care. Choice D is incorrect as rinsing the client's mouth with mouthwash several times a day may not be suitable for all clients and is not a standard recommendation for daily oral care.

5. Which clients are at risk for kidney problems? (Select all that apply.)

• A. Clients taking synthetic creatine supplements
• B. Clients taking metformin for diabetes mellitus
• C. Clients taking high-dose nonsteroidal anti-inflammatory drugs (NSAIDs) for chronic back pain
• D. Clients taking prenatal vitamins and using albuterol nebulizers

Correct answer: A

Rationale: Clients who take synthetic creatine supplements, metformin, and high-dose or long-term NSAIDs are at risk for kidney dysfunction. Synthetic creatine supplements can cause kidney damage, metformin may rarely cause lactic acidosis leading to renal impairment, and high-dose NSAIDs can lead to acute kidney injury. Prenatal vitamins and albuterol nebulizers are not known to significantly impact kidney function, thus do not pose a risk for kidney problems.
