Nursing Elites

1. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

2. A 23-year-old patient in the 27th week of pregnancy has been hospitalized on complete bed rest for 6 days. She experiences sudden shortness of breath, accompanied by chest pain. Which of the following conditions is the most likely cause of her symptoms?

• A. Myocardial infarction due to a history of atherosclerosis.
• B. Pulmonary embolism due to deep vein thrombosis (DVT).
• C. Anxiety attacks due to worries about her baby's health.
• D. Congestive heart failure due to fluid overload.

Correct answer: B

Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.

3. You are caring for a group of elderly clients, many of whom are affected by multiple chronic disorders and are also, at times, affected by some acute disorders that require medical and nursing attention. As you are caring for these clients, some will need a new medication regimen for an acute disorder. You should consider the fact that the elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to the elderly having a(n):

• A. Increased creatinine clearance.
• B. Impaired immune system.
• C. Decreased hepatic metabolism.
• D. Increased bodily fat

Correct answer: C

Rationale: The correct answer is 'Decreased hepatic metabolism.' The elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to a decrease in hepatic metabolism. This is caused by changes in hepatic functioning in the elderly, including decreased hepatic blood flow and functioning. Choice A, 'Increased creatinine clearance,' is incorrect as aging typically results in decreased, not increased, creatinine clearance. Choice B, 'Impaired immune system,' is not directly related to the increased risk of adverse drug reactions in the elderly. Choice D, 'Increased bodily fat,' is not a primary factor contributing to the increased risk of medication-related issues in the elderly population.

4. An adolescent brings a physician's note to school stating that he is not to participate in sports due to a diagnosis of Osgood-Schlatter disease. Which of the following statements about the disease is correct?

• A. The condition is not caused by the student's competitive swimming schedule.
• B. The student will most likely not require surgical intervention.
• C. The student experiences pain in the inferior aspect of the knee.
• D. The student is not trying to avoid participation in physical education.

Correct answer: C

Rationale: Osgood-Schlatter disease occurs in adolescents during the rapid growth phase when the infrapatellar ligament of the quadriceps muscle pulls on the tibial tubercle, causing pain and swelling in the inferior aspect of the knee. The condition is commonly caused by activities that require repeated use of the quadriceps, such as track and soccer. Choice A is incorrect because Osgood-Schlatter disease is not specifically linked to competitive swimming. Choice B is incorrect as surgical intervention is not usually necessary for this condition. Choice D is incorrect as the student is not trying to avoid physical education but is restricted from participating in sports due to the diagnosis of Osgood-Schlatter disease.

5. A client with schizophrenia seems to stop focusing during a conversation with a nurse and begins looking at the ceiling and talking to themselves. Which of the following actions should the nurse take?

• A. Stop the interview at this point and resume later when the client is better able to concentrate
• B. Ask the client, 'Are you seeing something on the ceiling?'
• C. Tell the client, 'You seem to be looking at something on the ceiling. I see something there, too.'
• D. Continue the interview without commenting on the client's behavior

Correct answer: B

Rationale: When a client with schizophrenia experiences a break in reality like staring at the ceiling and talking to themselves, the nurse should ask directly about the hallucination, as stated in choice B. By doing so, the nurse can assess the situation, identify the client's needs, and evaluate any potential risk for injury. Choices A, C, and D are incorrect. Stopping the interview (choice A) may not address the immediate concern of the hallucination. Providing false reassurance (choice C) or ignoring the behavior (choice D) does not actively address the client's altered perception of reality.
