Nursing Elites

1. A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?

• A. Family history of heart disease
• B. Overweight
• C. Smoking
• D. Age

Correct answer: A

Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.

2. A nurse is performing an end-of-shift count of narcotics kept in the locked cabinet. The narcotic log states there should be 26 oxycodone pills left, but there are only 24 in the drawer. What is the first action of the nurse?

• A. Perform the count again
• B. Contact the pharmacy to determine if the narcotic log is incorrect
• C. Check with the last nurse to sign out narcotics from the system
• D. Notify the house supervisor that narcotic medications are missing

Correct answer: A

Rationale: The first action the nurse should take in this situation is to perform the count again. This step is crucial to ensure there was no miscount during the initial check. By verifying the count, the nurse can confirm if there is indeed a discrepancy in the number of oxycodone pills. Contacting the pharmacy, checking with the last nurse, or notifying the house supervisor should only be considered after ensuring the count is accurate. It's important to rule out any human error before escalating the issue to others.

3. A child has recently been diagnosed with Duchenne muscular dystrophy (DMD). The parents are receiving genetic counseling prior to planning another pregnancy. Which of the following statements includes the most accurate information?

• A. Duchenne is an X-linked recessive disorder, so daughters have a 50% chance of being carriers and sons a 50% chance of developing the disease.
• B. Duchenne is an X-linked recessive disorder, so both daughters and sons have a 50% chance of developing the disease.
• C. Each child has a 1 in 4 (25%) chance of developing the disorder.
• D. Sons only have a 1 in 4 (25%) chance of developing the disorder.

Correct answer: A

Rationale: The correct answer is that Duchenne is an X-linked recessive disorder, meaning the affected gene is located on one of the two X chromosomes of a female carrier. If a son receives the X chromosome bearing the gene, he will develop the disease, giving him a 50% chance of being affected. Daughters, on the other hand, are not affected by Duchenne but have a 50% chance of being carriers since they inherit one copy of the defective gene from the mother. The other X chromosome is inherited from the father, who cannot be a carrier. Therefore, choice A is accurate. Choice B is incorrect because daughters do not develop the disease, and sons have a 50% chance of developing, not both having a 50% chance. Choice C is incorrect as it does not consider the X-linked inheritance pattern of Duchenne. Choice D is inaccurate as it incorrectly states that only sons have a 25% chance of developing the disorder, omitting the carrier status of daughters.

4. Which example best describes the concept of beneficence?

• A. A nurse provides pain medication for a client in the recovery room who is experiencing pain
• B. A client has an advanced directive in place stating that he does not want intubation if he needs CPR
• C. At the request of the client, a nurse does not inform the family about his cancer diagnosis
• D. A nurse withholds narcotic medication for a client in pain, knowing that he is currently disoriented

Correct answer: A

Rationale: Beneficence is the ethical principle of doing good and acting in the best interest of the client. Providing pain relief to a client in the recovery room who is experiencing pain aligns with beneficence as it promotes the client's well-being and comfort. Choice B is related to autonomy, where the client's wishes regarding treatment are respected. Choice C involves confidentiality and the client's right to privacy. Choice D represents nonmaleficence, as withholding pain medication from a client in pain could cause harm and goes against the principle of doing no harm.

5. 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.
