NCLEX PN Practice Tests Questions
Extract:
Question 1 of 5
The nurse is caring for a client with diabetic ketoacidosis (DKA). Which of the following acid-base imbalances would the nurse expect to assess in this client?
Correct Answer: A
Rationale: DKA causes metabolic acidosis due to excess ketone production from fat breakdown. Alkalosis and respiratory imbalances are not typical in DKA.
Question 2 of 5
The client has increased intracranial pressure with cerebral edema, and mannitol is administered. Which assessment should the nurse make to evaluate if a complication from the mannitol is occurring?
Correct Answer: D
Rationale: Pitting edema indicates fluid overload, a potential mannitol complication due to fluid shifts. High urine output is expected, and improving Glasgow Coma Scale is a therapeutic effect.
Question 3 of 5
In addition to standard precautions, a nurse should implement contact precautions for which client?
Correct Answer: A
Rationale: 60 year-old with herpes simplex. Clients who have herpes simplex infections must have contact precautions in addition to standard precautions because of the associated, potentially weeping, skin lesions. Contact precautions are used for clients who are infected by microorganisms that are transmitted by direct contact with the client, including hand or skin-to-skin contact.
Question 4 of 5
The RN charge nurse hands the LPN/LVN a syringe filled with medication that the RN has just drawn and asks the LPN/LVN to administer this to a client. How should the LPN/LVN respond?
Correct Answer: C
Rationale: Verifying the medication and checking the order ensures safe administration, adhering to medication safety protocols. Blind administration or refusal is unsafe or uncooperative.
Question 5 of 5
The nurse is caring for a client with type 2 diabetes mellitus who is receiving a thiazolidinedione. Which of the following findings would require immediate follow-up?
Correct Answer: A
Rationale: Thiazolidinediones (eg, rosiglitazone, pioglitazone) are oral antidiabetic medications used to manage hyperglycemia in clients with type 2 diabetes mellitus. Thiazolidinediones increase the sensitivity of insulin receptors, which improves insulin efficacy and prevents large rises in blood glucose after meals. It is a priority for the nurse to report signs of heart failure (eg, bilateral pitting edema, rapid weight gain, crackles) to the health care provider because thiazolidinediones can cause heart failure due to fluid retention. The client may require a lower thiazolidinedione dose or therapy with a different oral antidiabetic agent (eg, metformin).
