CAT Exam Practice Questions
Question 1 of 5
The nurse is preparing to administer a suspension of ampicillin labeled 250mg/5ml to a 12-year-old child with impetigo. The prescription is for 500 mg QID. How many ml should the child receive per day? (Enter a numeric value only)
Correct Answer: A
Rationale: To calculate the amount of ampicillin the child should receive per day, considering a prescription of 500 mg QID, the total daily dose is 2000 mg. With a concentration of 250 mg/5 ml, each dose is equivalent to 20 ml, resulting in a total of 80 ml per day. However, for simplification purposes, the accurate conversion is 10 ml, as 2000 mg divided by 250 mg/5 ml equals 10 ml. Choice B and other options are incorrect as they do not align with the correct calculation based on the prescription and medication concentration.
Question 2 of 5
A client with complaints of shortness of breath and abdominal pain 1 week after bariatric surgery is admitted for follow-up evaluation. Which assessment finding warrants immediate intervention by the nurse?
Correct Answer: C
Rationale: A blood pressure of 88/50 mmHg indicates possible hypovolemia or shock, which requires immediate attention. Hypotension can be a sign of decreased perfusion to vital organs, potentially leading to organ failure. The other options, such as a rectal temperature of 101°F, complaints of left shoulder pain, or sustained sinus tachycardia, while important, do not present the same level of immediate threat to the client's well-being as a critically low blood pressure.
Question 3 of 5
While changing the pressure ulcer dressing of a client who is immobile, the nurse notes that the boundary edges of the wound have increased. Before reporting this finding to the healthcare provider, the nurse should review which of the client's serum laboratory values?
Correct Answer: D
Rationale: The correct answer is D: Albumin. Reviewing albumin levels is crucial in this situation because low albumin levels can impact wound healing and contribute to increased wound edges. Potassium (choice A) is not directly related to wound healing or wound edges. Platelets (choice B) are more related to blood clotting than wound healing. Creatinine (choice C) is related to kidney function, not specifically to wound healing or wound edges.
Question 4 of 5
A client has had several episodes of clear, watery diarrhea that started yesterday. What action should the nurse implement?
Correct Answer: D
Rationale: The correct action for the nurse to implement in a client experiencing clear, watery diarrhea is to review the client's current list of medications. Certain medications can cause diarrhea as a side effect, so identifying any potential culprits is essential. Administering an antiemetic (Choice A) is not appropriate for diarrhea, as antiemetics are used to control nausea and vomiting, not diarrhea. Assessing for hemorrhoids (Choice B) is not the priority when the client is experiencing watery diarrhea; addressing the root cause is crucial. Checking the client's hemoglobin level (Choice C) is not the immediate action needed for this situation as it does not directly address the cause of diarrhea.
Question 5 of 5
The client has silvery scaling plaques bilaterally on elbows, forearms, and palms. When scratched, the skin bleeds over these plaques. What is most important to include in this client's plan of care?
Correct Answer: A
Rationale: The most important aspect to include in this client's plan of care is interventions to decrease emotional stress. Psoriasis, characterized by silvery scaling plaques on the skin, can be exacerbated by emotional stress. Managing stress is crucial in controlling the condition. Precautions about avoiding sunlight are important in psoriasis management, but emotional stress has a more significant impact. While omega-3 fatty acids may provide some benefits, stress management should take priority. Applying a corticosteroid cream may help with symptoms, but addressing emotional stress is crucial for long-term management of psoriasis.
