NCLEX RN Practice Questions Quizlet
1. An infant is brought to the clinic by his mother, who has noticed that he holds his head in an unusual position and always faces to one side. Which of the following is the most likely explanation?
- A. Torticollis, with shortening of the sternocleidomastoid muscle
- B. Craniosynostosis, with premature closure of the cranial sutures
- C. Plagiocephaly, with flattening of one side of the head
- D. Hydrocephalus, with increased head size
Correct answer: A
Rationale: The correct answer is torticollis, characterized by the shortening of the sternocleidomastoid muscle, limiting the range of motion of the neck and causing the chin to point to the opposing side. Craniosynostosis is the premature closure of cranial sutures, leading to an abnormal head shape but not necessarily affecting head position. Plagiocephaly is flattening of one side of the head due to external forces or positioning, not muscle shortening. Hydrocephalus presents with an increased head size due to the accumulation of cerebrospinal fluid, not with a fixed head position.
2. Mrs. O is seen for follow-up after an episode of acute pancreatitis. Her physician orders a serum amylase level and the result is 200 U/L. Which of the following is a potential cause of this result?
- A. The client is pregnant
- B. The client has hypertension
- C. The client is in renal failure
- D. The client has pancreatitis
Correct answer: D
Rationale: An elevated serum amylase level after pancreatitis may indicate another attack of the condition. It is common to order serum amylase as part of routine follow-up after pancreatitis. Elevated levels can also be seen in related gastrointestinal conditions like cholecystitis or an intestinal blockage. Therefore, in this case, the most likely cause of the elevated serum amylase level is a recurrence or ongoing pancreatitis. The other options, including pregnancy, hypertension, and renal failure, are not typically associated with an elevated serum amylase level in the context of follow-up after acute pancreatitis.
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. A client with a new prescription for lithium carbonate for bipolar disorder is being educated by a nurse on early indications of toxicity. The nurse should include which of the following manifestations in the teachings?
- A. Constipation
- B. Polyuria
- C. Rash
- D. Tinnitus
Correct answer: B
Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.
5. A nurse is required to float to another unit within the hospital where he is asked to care for a client on a ventilator. The nurse is uncomfortable with this assignment, as he has not had a ventilated client since nursing school. What is the nurse's most appropriate response?
- A. Explain to the nursing supervisor the level of discomfort and ask for a different assignment
- B. State that the client's needs are outside the nurse's scope of practice and request a different assignment
- C. Accept the assignment, asking for help when necessary
- D. Request to return to the home unit and send another nurse who can perform the job
Correct answer: A
Rationale: When floating to another unit and asked to take an assignment that falls outside a nurse's comfort zone, the nurse should notify the area supervisor of the level of discomfort and request a different assignment. Caring for ventilated clients typically falls within the scope of nursing practice; however, discomfort with the situation may not necessarily be overcome by accepting the assignment. Alternatively, the effects could be harmful to the client if the nurse is unfamiliar with this type of care. Requesting a different assignment is the most appropriate response in this situation, ensuring patient safety and the nurse's comfort level. Stating that the client's needs are outside the nurse's scope of practice (Choice B) may not be accurate, as caring for ventilated clients usually falls within the scope of nursing practice. Accepting the assignment (Choice C) without addressing the discomfort may compromise patient safety. Requesting to return to the home unit (Choice D) does not address the immediate need of caring for the ventilated client and may delay appropriate care.
