HESI CAT Exam

Correct Answer: A

Rationale: To calculate the maximum dosage in mg that the nurse should administer, multiply the dose per administration (0.4 mg) by the maximum number of doses allowed (5 doses): 0.4 mg/dose * 5 doses = 2 mg. Therefore, the nurse should administer a maximum dosage of 2 mg to the client. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

Correct Answer: D

Rationale: Observing for signs of depression is crucial in this patient's plan of care as depression can impact his overall recovery and management post-surgery. Depression is common in individuals struggling with weight management, diabetes mellitus, and hypertension. Monitoring for urinary incontinence (Choice A) is not the priority in this case as the patient is undergoing gastroplasty for weight management, not a urinary issue. Applying sequential compression stockings (Choice B) is important for preventing deep vein thrombosis in immobile patients but is not the priority in this scenario. Providing a wide variety of meal choices (Choice C) is not the most crucial intervention at this stage, as post-gastroplasty dietary restrictions are essential for successful weight management.

Correct Answer: C

Rationale: Vomiting is a common sign of digitalis toxicity and should be closely monitored. While tachycardia is a common sign of heart failure, it is not typically associated with digitalis toxicity (Choice A). Dyspnea (Choice B) and muscle cramps (Choice D) are not specific signs of digitalis toxicity and can be present in other conditions. Therefore, the presence of vomiting should raise concerns about digitalis toxicity in the child with heart failure.

Correct Answer: A

Rationale: To calculate the total dose of baclofen needed in a 24-hour period, multiply 15 mg by 3 doses, which equals 45 mg. Since the tablets are available in 10 mg strength, divide the total dose needed (45 mg) by the strength of each tablet (10 mg), which equals 4.5 tablets. Rounding off to the nearest tenth, the nurse should administer 4.5 tablets of 10 mg baclofen per day. Therefore, choice A is correct. Choices B, C, and D are irrelevant as they are not provided.

Correct Answer: A

Rationale: The correct order ensures proper aseptic technique and wound care to prevent infection. The first step is to remove the old dressing using clean gloves to prevent contamination. Discarding the gloves with the old dressing helps maintain cleanliness. Choices B, C, and D are incorrect because cleaning the wound, applying a new dressing, and securing it should come after removing the old dressing to maintain asepsis and prevent infection.
