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 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).

3. The OR nursing staff are preparing a client for a surgical procedure. The anesthesiologist has given the client medications, and the client has entered the induction stage of anesthesia. The nursing staff can expect which of the following symptoms and activities from the client during this time?

• A. Irregular breathing patterns
• B. Minimal heartbeat, dilated pupils
• C. Relaxed muscles, regular breathing, constricted pupils
• D. Euphoria, drowsiness, dizziness

Correct answer: D

Rationale: During the induction stage of anesthesia, the client may exhibit symptoms like euphoria, drowsiness, or dizziness. This stage occurs after the administration of medications by the anesthesiologist and ends when the client loses consciousness. Choice A is incorrect as irregular breathing patterns are not typically associated with the induction stage. Choice B is incorrect as minimal heartbeat and dilated pupils are not commonly observed during this stage. Choice C is incorrect as relaxed muscles, regular breathing, and constricted pupils are not indicative of the induction stage of anesthesia.

4. Which of the following clients is most likely ready to be dismissed from an inpatient care setting to home?

• A. A 65-year old male with urine output of 60cc in the past four hours
• B. A 2-month old female with a temperature of 100.6 rectally
• C. A 38-year old female who transitioned from IV TPN to full liquids six hours ago
• D. A 4-year old male with an oxygen saturation of 96% on room air

Correct answer: D

Rationale: Clients must meet a certain amount of set criteria before they will be discharged from a healthcare facility. Although guidelines may vary between locations, most healthcare facilities expect clients to have adequate oxygenation, nutrition, and elimination; and be free from fever, vomiting, and significant pain

5. Which behavior observed by the nurse indicates a suspicion that a depressed adolescent client may be suicidal?

• A. The adolescent gives away a DVD player and a cherished autographed picture of a performer.
• B. The adolescent runs out of group therapy, swearing at the group leader, and then goes to her room.
• C. The adolescent becomes angry while speaking on the phone and slams down the receiver.
• D. The adolescent gets angry with her roommate when the roommate borrows her clothes without asking.

Correct answer: A

Rationale: The correct answer is when the adolescent gives away a DVD player and a cherished autographed picture of a performer. This behavior is concerning because a depressed suicidal client often gives away things of value as a way of saying goodbye and wanting to be remembered. Choices B, C, and D all involve anger and acting-out behaviors, which are common in adolescents but do not specifically indicate suicidal ideation. Running out of group therapy, swearing, and going to her room, becoming angry and slamming the phone receiver, or getting upset when her roommate borrows her clothes are not clear indications of suicidal thoughts.
