Nursing Elites

1. A client is receiving education on cholesterol. Which of the following statements from the client indicates the need for further teaching?

• A. I would like my HDL levels to be over 50.
• B. It is better for me to have high HDL levels and low LDL levels.
• C. It is better for me to have high LDL levels and low HDL levels.
• D. My goal is to get my total cholesterol below 200.

Correct answer: C

Rationale: The correct answer is, 'It is better for me to have high LDL levels and low HDL levels.' This statement indicates a need for further teaching because high LDL levels contribute to atherosclerosis, while high HDL levels can protect against heart disease. The client should understand the importance of lowering LDL levels and increasing HDL levels to maintain good heart health. Choice A is correct as desiring HDL levels over 50 is a positive goal. Choice B is correct as it reflects the ideal scenario of high HDL and low LDL levels. Choice D is correct as a total cholesterol below 200 is a common goal for heart health. Therefore, Choice C is incorrect as it suggests an opposite and unhealthy relationship between LDL and HDL levels.

2. 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.

3. A new mother has some questions about phenylketonuria (PKU). Which of the following statements made by a nurse is not correct regarding PKU?

• A. A Guthrie test can check the necessary lab values.
• B. The urine has a high concentration of phenylpyruvic acid
• C. Mental deficits are often present with PKU
• D. The effects of PKU are reversible

Correct answer: D

Rationale: Phenylketonuria (PKU) is an inherited disorder that increases the levels of phenylalanine (a building block of proteins) in the blood. If PKU is not treated, phenylalanine can build up to harmful levels in the body, causing intellectual disability and other serious health problems. The signs and symptoms of PKU vary from mild to severe. The most severe form of this disorder is known as classic PKU. Infants with classic PKU appear normal until they are a few months old. Without treatment, these children develop a permanent intellectual disability. Seizures, delayed development, behavioral problems, and psychiatric disorders are also common. Untreated individuals may have a musty or mouse-like odor as a side effect of excess phenylalanine in the body. Children with classic PKU tend to have lighter skin and hair than unaffected family members and are also likely to have skin disorders such as eczema. The effects of PKU stay with the infant throughout their life (via Genetic Home Reference).

4. Which of the following is an example of a living will?

• A. A client's son has been appointed to make his healthcare decisions if he becomes incapacitated
• B. A client has designated which of his children will receive his home and property before he dies
• C. A client has instructions that he does not want to be resuscitated through chest compressions if his heart stops beating
• D. A client designates what type of burial or cremation services he would want after his death

Correct answer: C

Rationale: A living will is a type of advanced directive that a client develops to stipulate his preferences for healthcare in the event that he is unable to do so. This includes specific instructions about medical treatments in certain situations. Choice C is the correct answer as it reflects a scenario where the client has clearly outlined their preference regarding resuscitation through chest compressions. Choices A, B, and D do not pertain to a living will. Choice A involves a healthcare proxy or agent, choice B involves a will or estate planning, and choice D involves funeral or burial arrangements, which are not part of a living will.

5. A nonimmunized child appears at the clinic with a visible rash. Which of the following observations indicates the child may have rubeola (measles)?

• A. Small blue-white spots are visible on the oral mucosa.
• B. The rash begins on the trunk and spreads outward.
• C. There is low-grade fever.
• D. The lesions have a "teardrop-on-a-rose-petal"? appearance.

Correct answer: A

Rationale: The presence of small blue-white spots on the oral mucosa, known as Koplik's spots, is characteristic of measles (rubeola) infection. These spots typically appear on the buccal mucosa opposite the second molars, 1-2 days before the rash onset, and last until 2 days after the rash appears. While Koplik's spots are pathognomonic for measles, their absence does not rule out the diagnosis. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because the rash pattern, presence of low-grade fever, and characteristic appearance of lesions are not specific indicators of measles infection.
