Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A nurse is planning care for a client who has chronic kidney disease. Which finding indicates the need for hemodialysis?

• A. BUN 14 mg/dL
• B. Serum potassium 4.2 mEq/L
• C. Serum creatinine 5 mg/dL
• D. Serum calcium 9 mg/dL

Correct answer: C

Rationale: The correct answer is C. A serum creatinine level of 5 mg/dL is significantly elevated and indicates the need for hemodialysis to help filter waste products from the blood. Elevated creatinine levels suggest impaired kidney function and the inability to effectively filter waste from the body. Choices A, B, and D are within normal ranges and do not indicate the need for immediate hemodialysis in a client with chronic kidney disease.

3. A nurse is preparing to perform a routine abdominal assessment for a client. Which action should the nurse take?

• A. Perform palpation before auscultation
• B. Perform percussion before auscultation
• C. Perform palpation after auscultation
• D. Perform inspection after auscultation

Correct answer: C

Rationale: The correct answer is C: Perform palpation after auscultation. When conducting an abdominal assessment, the correct sequence is inspection, auscultation, percussion, and then palpation. Inspecting the abdomen allows the nurse to observe any visible abnormalities, followed by listening for bowel sounds during auscultation. Percussion helps assess the density of abdominal contents before palpation for tenderness, masses, or organ enlargement. Choices A, B, and D are incorrect because palpation should always come last in the sequence of an abdominal assessment.

4. A nurse is caring for a group of clients in a long-term care facility. Which of the following situations should the nurse recognize as a safety hazard?

• A. A client’s wrist restraints tied to the bed rails
• B. A client’s bedside table placed across the foot of the bed
• C. A meal tray left at the bedside from breakfast
• D. A call light extension cord pinned to the bedspread

Correct answer: A

Rationale: The correct answer is A. Tying wrist restraints to the bed rails is a safety hazard because if the bed rails are lowered, the restraints can tighten and cause injury or asphyxiation. Choice B, placing a bedside table across the foot of the bed, may not be ideal for convenience but does not pose a direct safety hazard. Choice C, leaving a meal tray at the bedside from breakfast, is more of an infection control issue than an immediate safety hazard. Choice D, having a call light extension cord pinned to the bedspread, is also not a direct safety hazard unless it poses a risk of entanglement or tripping, which is not indicated in the scenario.

5. A nurse is providing teaching to a client who is at 34 weeks of gestation and is scheduled for a nonstress test. Which of the following statements should the nurse plan to make?

• A. You will not receive medication through an IV for this test.
• B. You should expect the test to take about 30 minutes.
• C. You do not need to eat or drink for 4 hours prior to the test.
• D. This test will help determine if your baby's lungs are mature.

Correct answer: B

Rationale: The correct statement for the nurse to make is choice B, 'You should expect the test to take about 30 minutes.' The nonstress test is used to assess fetal well-being by monitoring fetal heart rate in response to movements. Choice A is incorrect because medications are not typically administered during a nonstress test. Choice C is incorrect as there is no need for the client to fast before the test. Choice D is incorrect because determining fetal lung maturity is usually done through other tests, not the nonstress test.
