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: 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).

2. Which of the following situations might warrant a laboratory magnesium level?

• A. Hyperthyroidism
• B. Arthritis
• C. Ulcerative colitis
• D. Depression

Correct answer: C

Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.

3. A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?

• A. Peaked T waves on the ECG
• B. Muscle spasms
• C. Constipation
• D. A prominent U wave on the ECG

Correct answer: A

Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.

4. Which example best describes a nurse who exhibits moral courage?

• A. A nurse feels angry when a parent refuses important treatment for his child.
• B. A nurse considers seeking help for depression when she feels she cannot meet the needs of her clients in the oncology unit.
• C. A nurse contacts a physician for further orders when he fails to order comfort measures for a client with a terminal illness.
• D. A nurse is frustrated when the laboratory is slow in responding to an order for a stat blood glucose.

Correct answer: C

Rationale: Moral courage involves taking action to do what is right, even when there might be negative consequences. The nurse who contacted a physician for further orders acted as a client advocate to seek help, even though she may have faced consequences such as lost time, decreased productivity, or criticism from the physician. Choices A, B, and D do not directly involve advocating for a client's needs or challenging a situation that goes against ethical standards. Feeling angry, seeking help for personal issues, or being frustrated with work processes do not necessarily demonstrate moral courage in the context of nursing practice.

5. A client on an acute mental health unit reports hearing voices that are stating, "kill your doctor"?. Which of the following actions should the nurse take first?

• A. Encourage the client to participate in group therapy on the unit.
• B. Initiate one-to-one observation of the client.
• C. Focus the client on reality.
• D. Notify the provider of the client's statement.

Correct answer: B

Rationale: When a client experiences command hallucinations, such as being told to harm someone, the priority is ensuring the safety of the client and others. Initiating one-to-one observation allows for close monitoring and intervention to prevent harm. Encouraging participation in group therapy may not be appropriate or safe at this time. Focusing the client on reality may not be effective when experiencing hallucinations, and notifying the provider should come after immediate safety measures have been taken.
