Question 1 of 5

A client who is brought to the emergency department has experienced a burn covering greater than 25% of his total body surface area (TBSA). When reviewing the laboratory results drawn on the client, which value should the nurse most likely expect to note?

Correct Answer: A

Rationale: Extensive burns covering greater than 25% of the TBSA result in generalized body edema in both burned and nonburned tissues and a decrease in circulating intravascular blood volume. Hematocrit levels elevate in the first 24 hours after injury (the emergent phase) as a result of hemoconcentration from the loss of intravascular fluid. The normal hematocrit is 42 to 52% (0.42-0.52) in the male and 37 to 47% (0.37-0.47) in the female. The normal albumin is 3.5-5 g/dL (35-50 g/L). The normal sodium level is 135 to 145 mEq/L (135-145 mmol/L). The normal WBC count is 5000 to 10,000 mm^3 (5-10 x 10^9/L).

Question 2 of 5

The client has been prescribed lisinopril (Prinivil) to treat hypertension. The nurse should assess the client for which of the following electrolyte imbalances?

Correct Answer: A

Rationale: Lisinopril, an ACE inhibitor, can cause hyponatremia due to its effects on sodium excretion. Hypocalcemia and hypermagnesemia are not commonly associated with this medication.

Question 3 of 5

The nurse should instruct a client who is taking dexamethasone (Decadron) and furosemide (Lasix) to report:

Correct Answer: B

Rationale: Muscle weakness is a serious side effect of dexamethasone (steroid-induced myopathy) and furosemide (potassium loss), requiring prompt reporting.

Question 4 of 5

The nurse is beginning the shift and is assessing the oxygen exchange on a neonate. The nurse reviews the chart for pulse oximetry reading for the last 8 hours. The pulse oximetry reading at 3:30 p.m. is 75%. What should the nurse do first?

Question Image

Correct Answer: C

Rationale: A pulse oximetry reading of 75% is concerning but may be due to probe misplacement. Reassessing the reading first confirms accuracy before escalating to invasive measures like blood gases.

Question 5 of 5

A client with chronic kidney disease is on a low-potassium diet. Which food should the nurse advise the client to avoid?

Correct Answer: B

Rationale: Bananas are high in potassium, which must be limited in chronic kidney disease to prevent hyperkalemia.
