Question 1 of 5
A client is admitted to the emergency department with a loss of consciousness with unknown etiology. The nurse expects to perform which laboratory test to assist in determining etiology?
Correct Answer: C
Rationale: Serum glucose is critical to rule out hypoglycemia or hyperglycemia as causes of unconsciousness. Cholesterol (
A), alkaline phosphatase (
B), and urinalysis (
D) are less urgent.
Question 2 of 5
A client with vaginal cancer is being treated with a radioactive vaginal implant. The client's husband asks the nurse if he can spend the night with his wife. The nurse should explain that:
Correct Answer: D
Rationale: Radioactive implants emit radiation posing a risk to others. Visitation is limited to short periods (e.g. 30 minutes) to minimize radiation exposure. The other options do not address the safety concern related to radiation.
Question 3 of 5
A 26-year-old male client is brought by his wife to the emergency department (ED) unconscious. Blood is drawn for a stat blood count (CBC), fasting blood sugar level, and electrolytes. An indwelling urinary catheter is inserted. He has a history of type 1 diabetes (insulin-dependent diabetes mellitus [IDDM]). A diagnosis of ketoacidosis is made. Stat lab values reveal a blood sugar level of 520 mg/dL. Which of the following should the nurse expect to administer in the ER?
Correct Answer: C
Rationale: Regular insulin is the fastest acting-insulin; when given IV, it will immediately act to decrease blood sugar. Regular insulin is given to decrease blood glucose levels by promoting metabolism of glucose, inhibiting lipolysis and formation of ketone bodies.
Question 4 of 5
The client is admitted with a diagnosis of placenta accreta. Which complication is most likely to occur?
Correct Answer: D
Rationale: Placenta accreta where the placenta abnormally adheres to the uterine wall increases the risk of maternal hemorrhage (during delivery) fetal distress (from placental dysfunction) and preterm labor (from interventions). All are potential complications.
Question 5 of 5
A 29-year-old client is admitted for a hysterectomy. She has repeatedly told the nurses that she is worried about having this surgery, has not slept well lately, and is afraid that her husband will not find her desirable after the surgery. Shortly into the preoperative teaching, she complains of a tightness in her chest, a feeling of suffocation, lightheadedness, and tingling in her hands. Her respirations are rapid and deep. Assessment reveals that the client is:
Correct Answer: D
Rationale: Classic symptoms of a heart attack include heaviness or squeezing pain in the chest, pain spreading to the jaw, neck, and arm. Nausea and vomiting, sweating, and shortness of breath may be present. The client does not exhibit these symptoms. Clients suffering from anxiety or fear prior to surgical procedures may develop hyperventilation. This client is not seeking attention. Symptoms of complete airway obstruction include not being able to speak, and no airflow between the nose and mouth. Breath sounds are absent. Tightness in the chest; a feeling of suffocation; lightheadedness; tingling in the hands; and rapid, deep respirations are signs and symptoms of hyperventilation. This is almost always a manifestation of anxiety.
