Nursing Elites

1. 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: The effects of PKU are reversible

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).

2. Research participants are involved in a trial that incidentally separates them into two groups. One group receives an intervention, while the other group does not. Both groups are compared for outcomes. What type of research method is this?

• A. Experimental design
• B. Double-blind experiment
• C. Randomized controlled trial
• D. Repeated measures design

Correct answer: Randomized controlled trial

Rationale: A randomized controlled trial is a research method in which participants are randomly assigned to either a treatment or control group. This design helps eliminate bias and allows for the comparison of outcomes between the two groups. In this scenario, where participants are separated into intervention and non-intervention groups for comparison, it aligns with the characteristics of a randomized controlled trial. The key feature distinguishing it from the other options is the random assignment of participants to groups, ensuring that both groups are comparable at the start of the study. Double-blind experiments involve blinding both participants and researchers to treatment allocation, which is not explicitly mentioned in the scenario. Experimental design refers to a broader category that includes various types of research designs beyond just randomized controlled trials. Repeated measures design involves collecting multiple observations from the same participants over time, which is not the case described in the scenario.

3. A 58-year-old client is being tested for rheumatoid arthritis. Her physician orders an erythrocyte sedimentation rate (ESR). Which of the following results is most likely to be associated with arthritis?

• A. 5 mm/hr
• B. 12 mm/hr
• C. 28 mm/hr
• D. 40 mm/hr

Correct answer: 40 mm/hr

Rationale: The erythrocyte sedimentation rate (ESR) measures levels of inflammation in the body. Elevated ESR levels are commonly seen in autoimmune conditions like rheumatoid arthritis due to the presence of inflammation. In women over 50 years old, a normal ESR is typically below 30 mm/hr. Therefore, a result of 40 mm/hr is more indicative of arthritis in a 58-year-old individual. Choices A, B, and C are below the normal ESR range for a woman of this age and would not be as strongly associated with arthritis.

4. The nurse teaches a patient about the transmission of pulmonary tuberculosis (TB). Which statement, if made by the patient, indicates that teaching was effective?

• A. I will avoid being outdoors whenever possible.
• B. My husband will be sleeping in the guest bedroom.
• C. I will take the bus instead of driving to visit my friends.
• D. I will keep the windows closed at home to contain the germs.

Correct answer: My husband will be sleeping in the guest bedroom.

Rationale: To prevent the transmission of pulmonary tuberculosis, it is important for the infected individual to minimize exposure to close contacts and household members. Sleeping alone in a separate room, like the guest bedroom, is an effective measure. The other choices are not ideal: Choice A is incorrect because spending time outdoors is encouraged for ventilation; Choice C is incorrect as using public transportation increases the risk of transmission; Choice D is incorrect because keeping windows closed limits ventilation, which is necessary to reduce the concentration of infectious particles in the air.

5. A writer is admitted for the second time accompanied by his wife. He is demanding, arrogant, talks fast, and is hyperactive. Initially, the nurse should plan this for a manic client:

• A. Set realistic limits to the client’s behavior
• B. Repeat verbal instructions as often as needed
• C. Allow the client to express feelings to relieve tension
• D. Assign a staff member to be with the client at all times to help maintain control

Correct answer: Set realistic limits to the client’s behavior

Rationale: For a manic client who is demanding, arrogant, talks fast, and is hyperactive, setting realistic limits to the client’s behavior is essential to ensure safety as manic clients may engage in injurious activities. A quiet environment and consistent, firm limits help to maintain control. While repeating verbal instructions may be necessary due to distractibility, it is not the priority compared to setting limits for safety. Allowing the client to express feelings is important, but only non-destructive methods of expression should be permitted. Assigning a staff member to be with the client at all times is not a realistic approach as it may not always be feasible or necessary for managing manic behavior effectively.
