HESI RN CAT Exam Quizlet
1. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?
- A. 10 ml
- B. 12.5 ml
- C. 15 ml
- D. 17.5 ml
Correct answer: B
Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
2. The nurse is performing a physical assessment of a client with a history of smoking and notes a barrel chest. Which action is most important for the nurse to take next?
- A. Assess the client's oxygen saturation level
- B. Teach the client pursed-lip breathing techniques
- C. Determine the client's history of lung disease
- D. Obtain an arterial blood gas sample
Correct answer: A
Rationale: Corrected Rationale: Assessing the client's oxygen saturation level is crucial when a nurse identifies a barrel chest. A barrel chest is often associated with chronic obstructive pulmonary disease (COPD), which can lead to impaired gas exchange and decreased oxygen saturation. Monitoring the oxygen saturation level will provide immediate information on the client's respiratory status. Teaching pursed-lip breathing techniques, determining lung disease history, and obtaining arterial blood gas samples are important interventions but assessing oxygen saturation takes precedence in this scenario due to its direct impact on the client's respiratory function.
3. A nurse is preparing to insert an indwelling urinary catheter in a female client. Which action should the nurse take to maintain sterile technique?
- A. Apply sterile gloves before inserting the catheter
- B. Use sterile gloves to insert the catheter
- C. Clean the urinary meatus with an antiseptic solution
- D. Place the drainage bag above the level of the bladder
Correct answer: B
Rationale: Using sterile gloves to insert the catheter is crucial to maintaining sterile technique. Sterile gloves help prevent the introduction of microorganisms during the insertion process. Applying sterile gloves before cleansing the perineal area (Choice A) is important but not specific to maintaining sterility during catheter insertion. Cleaning the urinary meatus with an antiseptic solution (Choice C) is a step in the catheterization process but does not solely ensure sterile technique. Placing the drainage bag above the level of the bladder (Choice D) is incorrect; the bag should be placed below the level of the bladder to facilitate urine drainage.
4. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2°F and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: Elevated urine specific gravity is a sign of dehydration in children. In the scenario provided, the child is experiencing increased stool frequency, liquid consistency, fever, and vomiting, indicating fluid loss and potential dehydration. Occult blood in the stool may suggest gastrointestinal bleeding but is not a direct indicator of dehydration. Abdominal distention can be seen in various conditions and is not specific to dehydration. Hyperactive bowel sounds are more commonly associated with increased bowel motility, not necessarily dehydration.
5. Which nursing diagnosis has the highest priority when planning care for a client in cardiogenic shock?
- A. Risk for imbalanced body temperature
- B. Excess fluid volume
- C. Fatigue
- D. Ineffective Tissue Perfusion
Correct answer: D
Rationale: In cardiogenic shock, the priority nursing diagnosis is Ineffective Tissue Perfusion. This diagnosis indicates that the client is not receiving adequate oxygenated blood to tissues, putting vital organs at risk. Addressing ineffective tissue perfusion is crucial to prevent organ damage and ensure the client's survival. The other options, such as 'Risk for imbalanced body temperature,' 'Excess fluid volume,' and 'Fatigue,' are important but secondary to the immediate threat of inadequate tissue perfusion in cardiogenic shock.
