NCLEX RN Exam Review Answers
1. The mother of a newborn infant with hypospadias asks the nurse why circumcision cannot be performed. Which is the most appropriate response by the nurse?
- A. Circumcision will cause an infection.
- B. Circumcision is not performed in a newborn.
- C. Circumcision will cause difficulty with urination.
- D. Circumcision has been delayed to save tissue for surgical repair.
Correct answer: D
Rationale: The reason circumcision is not performed in a newborn with hypospadias is that the dorsal foreskin tissue will be needed for the surgical repair of hypospadias. Delaying circumcision allows for the preservation of tissue that will be crucial for the corrective surgery. This surgical repair is typically done within the first year of life to minimize the psychological impact on the child. Choices A, B, and C are incorrect as they do not address the specific reason for delaying circumcision in this case.
2. The nurse is preparing to administer an enteral feeding to a client via a nasogastric feeding tube. The most important action of the nurse is:
- A. Verify correct placement of the tube
- B. Check that the feeding solution matches the dietary order
- C. Aspirate gastric contents to determine the amount of the last feeding remaining in the stomach
- D. Ensure that the feeding solution is at room temperature
Correct answer: A
Rationale: The most crucial action for the nurse when preparing to administer enteral feeding via a nasogastric tube is to verify the correct placement of the tube. Proper placement of the tube is vital to prevent complications such as aspiration into the lungs. The definitive methods to confirm the position of the nasogastric tube include visualization through an x-ray or aspirating stomach contents and checking their pH (usually pH 1 to 5). Aspirated stomach content can also be tested for bilirubin to confirm placement in the stomach. Choice B, checking that the feeding solution matches the dietary order, is important for ensuring the correct nutrition is provided but is not as critical as verifying tube placement to prevent potential harm. Choice C, aspirating gastric contents to determine the amount of the last feeding remaining in the stomach, is a common nursing practice but is not the most crucial action when compared to ensuring correct tube placement. Choice D, ensuring that the feeding solution is at room temperature, is relevant for patient comfort and preventing thermal injury but is not as essential as confirming correct tube placement to prevent serious complications.
3. The nurse is performing a neurological assessment on a client post right cerebrovascular accident. Which finding, if observed by the nurse, would warrant immediate attention?
- A. Decrease in level of consciousness
- B. Loss of bladder control
- C. Altered sensation to stimuli
- D. Emotional lability
Correct answer: A
Rationale: A decrease in the level of consciousness is a critical finding that would warrant immediate attention in a client post right cerebrovascular accident. This change may indicate an increase in intracranial pressure, leading to inadequate oxygenation of the brain. It could also reveal the presence of a transient ischemic attack, which may signal an impending thrombotic cerebrovascular accident. Loss of bladder control (choice B) can be managed and monitored but does not indicate an immediate threat to the client's life. Altered sensation to stimuli (choice C) can be a concerning finding but may not require immediate attention unless it affects the client's safety. Emotional lability (choice D) may be distressing for the client but does not pose an immediate risk to their health compared to a decrease in the level of consciousness.
4. The nurse is caring for an infant with cryptorchidism. The nurse anticipates that the most likely diagnostic study to be prescribed would be the one that assesses which item?
- A. Babinski reflex
- B. DNA synthesis
- C. Urinary function
- D. Chromosomal analysis
Correct answer: C
Rationale: Cryptorchidism, also known as undescended testes, may be caused by hormonal deficiency, intrinsic testicular abnormality, or a structural problem. Diagnostic studies for cryptorchidism typically involve assessing urinary function because the kidneys and testes originate from the same embryonic tissue. The Babinski reflex is a test for neurological function and is not relevant to evaluating cryptorchidism. DNA synthesis and chromosomal analysis are not commonly used diagnostic tests for cryptorchidism, as they are unrelated to the disorder's etiology or presentation.
5. What is the cause of meningitis that is fatal in half of the infected patients?
- A. Virus
- B. Bacteria
- C. Fungus
- D. Noninfectious agent
Correct answer: B
Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.
