CAT Exam Practice
1. 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)
- A. 10
- B.
- C.
- D.
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.
2. Which client’s vital signs indicate increased intracranial pressure (ICP) that the nurse should report to the healthcare provider?
- A. P 70, BP 120/60 mmHg; P 100, BP 90/60 mmHg; rapid respirations.
- B. P 55, BP 160/70 mmHg; P 50, BP 194/70 mmHg; irregular respirations.
- C. P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations.
- D. P 110, BP 130/70 mmHg; P 100, BP 110/70 mmHg; shallow respirations.
Correct answer: C
Rationale: Choice C is the correct answer. The vital signs presented (P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations) indicate increased intracranial pressure (ICP), which can be a serious condition requiring immediate medical attention. Kussmaul respirations are deep and labored breathing patterns associated with metabolic acidosis and can be a late sign of increased ICP. Choices A, B, and D do not demonstrate vital sign patterns consistent with increased ICP. Choice A shows variations in blood pressure and pulse rate but does not provide a clear indication of increased ICP. Choice B displays fluctuations in blood pressure and pulse rate with irregular respirations, but these vital signs do not specifically suggest increased ICP. Choice D presents relatively stable vital signs with shallow respirations, which do not align with the typical vital signs seen in increased ICP.
3. The charge nurse of a cardiac telemetry unit is assigning client care to a registered nurse (RN) and a practical nurse (PN). Which client should be assigned to the RN?
- A. One day after a permanent pacemaker insertion, a client's telemetry monitor shows a pacer rhythm.
- B. Two hours after undergoing cardioversion, a client's telemetry monitor shows a normal sinus rhythm.
- C. A client started on carvedilol the previous day for heart failure has controlled atrial fibrillation.
- D. Four hours after admission, a client with syncope shows complete heart block on the telemetry monitor.
Correct answer: D
Rationale: The correct answer is D because complete heart block is a critical condition that requires immediate assessment and management by a registered nurse (RN). In complete heart block, there is a significant conduction disturbance that can lead to serious complications. The RN is better equipped to handle such complex and potentially life-threatening situations. Choices A, B, and C involve less critical conditions that can be managed by a practical nurse (PN) under the supervision of the RN. Therefore, assigning the client with complete heart block to the RN ensures prompt and appropriate intervention.
4. Which action should the nurse include in the plan of care for a client receiving acyclovir (Zovirax) IV for treatment of herpes zoster (shingles)?
- A. Initiate cardiac telemetry monitoring
- B. Maintain continuous pulse oximetry
- C. Perform capillary glucose measurements
- D. Monitor serum creatinine levels
Correct answer: D
Rationale: The correct answer is D: Monitor serum creatinine levels. Acyclovir can lead to nephrotoxicity, making it essential to monitor kidney function through serum creatinine levels. While cardiac telemetry monitoring (choice A) and maintaining continuous pulse oximetry (choice B) are important in certain conditions, they are not directly related to acyclovir therapy for herpes zoster. Performing capillary glucose measurements (choice C) is not a priority when administering acyclovir for herpes zoster. Monitoring serum creatinine levels is crucial to detect any potential renal issues early, as the drug's nephrotoxic potential requires close monitoring of kidney function.
5. Which techniques should be used to administer an intradermal (ID) injection for a Mantoux test to screen for tuberculosis (TB)? Select all that apply.
- A. Observe for an intradermal bleed after the antigen is injected
- B. Select an ID site using the volar surface of the forearm
- C. Use a 26 or 27-gauge needle with a length of 1/4 to 5/8 inches on a 1 ml calibrated syringe
- D. Ensure that the needle is inserted into the skin with the bevel up
Correct answer: A
Rationale: Observing for an intradermal bleed after the antigen is injected is a proper technique for an ID injection. This is important to confirm the correct placement of the injection. Choice B is correct because the recommended site for an ID injection for a Mantoux test is the volar surface of the forearm. Choice C is incorrect because the standard needle size for an ID injection is usually 26 or 27 gauge with a length of 1/4 to 5/8 inches, not 25 gauge with a length of 1/2 inch. Choice D is incorrect because the needle should be inserted into the skin with the bevel facing up, not down.
