An 80-year-old male client with multiple chronic health problems becomes disoriented, agitated, and combative 24 hours after being admitted to the hospital. What nursing intervention is most important to include in this client's plan of care?

A. Request a psychiatric consultation for the client.

B. Reorient the client frequently to time, place, and person.

C. Administer prescribed antipsychotic medications to reduce agitation.

D. Obtain an order for a sitter to stay with the client.

Correct Answer: B
Rationale: Reorienting the client frequently is the most important nursing intervention in this scenario. It helps reduce confusion and agitation, which are common symptoms of acute delirium in hospitalized elderly clients. Requesting a psychiatric consult (choice A) may be necessary if the reorientation does not improve the client's condition or if there are underlying psychiatric concerns, but reorientation should be attempted first. Administering antipsychotic medications (choice C) should not be the initial intervention as they can have adverse effects in elderly individuals. Obtaining a sitter (choice D) may provide support but does not directly address the client's disorientation and agitation.

The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?

• A. Serum creatinine of 1.5 mg/dL
• B. Serum sodium of 136 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Hemoglobin of 12 g/dL

Correct Answer: C
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.

A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value is most concerning?

• A. Serum glucose of 300 mg/dl
• B. Serum bicarbonate of 18 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Serum sodium of 135 mEq/L

Correct Answer: C
Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with DKA as it may indicate worsening hyperkalemia, requiring immediate intervention. Elevated serum potassium levels can lead to life-threatening cardiac arrhythmias. While elevated glucose and low bicarbonate are characteristic of DKA, hyperkalemia poses a higher immediate risk. Serum sodium within the normal range is not typically a primary concern in DKA.

The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct Answer: A
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

A 10-year-old who has terminal brain cancer asks the nurse, 'What will happen to my body when I die?' How should the nurse respond?

• A. Your mother and father will be here soon. Talk to them about that.'
• B. Why do you want to know about what will happen to your body when you die?'
• C. The heart will stop beating and you will stop breathing.'
• D. Are you concerned about where your spirit will go?'

Correct Answer: C
Rationale: The correct response when a terminally ill child asks about what will happen to their body when they die is to provide a truthful and straightforward answer. Choice C, 'The heart will stop beating and you will stop breathing,' is the best response because it offers a simple and honest explanation without delving into spiritual or emotional aspects that may be confusing or distressing to the child. Choices A and D deflect the question and do not address the child's inquiry directly. Choice B, 'Why do you want to know about what will happen to your body when you die?' may come across as dismissive or evasive, rather than providing the clear information the child is seeking.
