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. 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.

3. At the beginning of her shift in a long-term care facility, which of the following clients should a nurse check on first?

• A. A 91-year-old man who needs help eating breakfast
• B. An 86-year-old man who has been incontinent in his bed
• C. An 82-year-old woman who needs IV antibiotics
• D. A 75-year-old man who is recovering from an injury and needs an ice pack

Correct answer: C

Rationale: When prioritizing care in a long-term care facility, the nurse must consider tasks that require their immediate attention and cannot be delegated. Administering IV antibiotics is a critical nursing task that only the nurse can perform, ensuring the timely and correct delivery of medication to the patient. While assisting with breakfast, managing incontinence, and providing an ice pack are important, these tasks can be delegated to other healthcare team members, allowing the nurse to address the client needing IV antibiotics first to ensure effective treatment and patient safety.

4. As a nurse, you have been assigned to take over as charge nurse without any report after the previous charge nurse fell during her shift and was taken to the emergency room. At the end of the shift, you have made the assignments for the next shift's nurses and posted them. As the nurses come in, they begin to complain that the assignments make no sense based on patient acuity. One refuses to take her assignment and threatens to go home. What could you have done to prevent their dissatisfaction?

• A. Reviewed the notes of the previous charge nurse
• B. Tried to contact the previous charge nurse in the emergency room
• C. Collaborated with the nurse manager
• D. Collaborated with the other nurses on your shift

Correct answer: D

Rationale: Collaborating with the other nurses on your shift would have permitted them to provide the most updated information regarding patient status and acuity. Requesting their input into creating assignments would have provided shared governance and assurance that the unit staffing was arranged appropriately. Reviewing the notes of the previous charge nurse might not capture the real-time changes in patient conditions. Trying to contact the previous charge nurse in the emergency room may not be feasible or timely. Collaborating with the nurse manager could be helpful, but involving the nurses directly impacted by the assignments would have been more effective in addressing their concerns and ensuring appropriate patient care.

5. Which of the following types of antipsychotic medications is most likely to produce extrapyramidal effects?

• A. Atypical antipsychotic drugs
• B. First-generation antipsychotic drugs
• C. Third-generation antipsychotic drugs
• D. Dopamine system stabilizers

Correct answer: B

Rationale: The correct answer is first-generation antipsychotic drugs. These drugs are potent antagonists of D2, D3, and D4 receptors, making them effective in treating target symptoms but also leading to numerous extrapyramidal side effects due to the blockade of D2 receptors. Atypical or second-generation antipsychotic drugs, as mentioned in choice A, are relatively weak D2 blockers, which results in a lower incidence of extrapyramidal side effects. Third-generation antipsychotic drugs, as in choice C, and dopamine system stabilizers, as in choice D, are not typically associated with significant extrapyramidal effects compared to first-generation antipsychotics.
