Question 1 of 5
The nurse notes hyperventilation in a client with a thermal injury. She recognizes that this may be a reaction to which of the following medications if applied in large amounts?
Correct Answer: B
Rationale: Mafenide acetate can cause metabolic acidosis, leading to compensatory hyperventilation. The other medications listed do not typically cause this reaction.
Question 2 of 5
A client is admitted to the labor room. She is dilated 4 cm. She is placed on electric fetal monitoring. Which of the following observations necessitates notifying the physician?
Correct Answer: A
Rationale: These are tetanic in nature and can cause rupture of the uterus. The FHR decreases during contractions owing to vasoconstriction and should recover after the contraction. Beat-to-beat variability is a normal finding and demonstrates fetal well-being. The FHR may decrease at the beginning of a contraction owing to head compression.
Question 3 of 5
The nurse caring for a client in shock recognizes that the glomerular filtration rate of the kidneys will fail if the client's mean arterial pressure falls below which of the following levels?
Correct Answer: D
Rationale: A mean arterial pressure (MAP) below 80 mmHg compromises renal perfusion, leading to glomerular filtration failure. Higher MAPs (A, B,
C) maintain adequate kidney function.
Question 4 of 5
The nurse is assessing a trauma client in the emergency room when she notes a penetrating abdominal wound with exposed viscera. The nurse should:
Correct Answer: B
Rationale: Exposed viscera should be covered with sterile saline-soaked gauze to keep them moist and prevent infection until surgical repair. Replacing contents or using non-sterile/petroleum dressings is unsafe.
Question 5 of 5
A client has had a unilateral adrenalectomy to remove a tumor. The most important measurement in the immediate post-operative period for the nurse to take is:
Correct Answer: A
Rationale: Adrenalectomy can disrupt cortisol and aldosterone production leading to blood pressure instability (e.g. hypotension from adrenal insufficiency). Monitoring blood pressure is critical to detect and manage these changes promptly.
