1. The nurse is caring for a client with a diagnosis of pneumonia who has been febrile for 24 hours. Which data is most important for the nurse to obtain in determining the client's fluid status?
- A. Daily intake and output
- B. Skin turgor
- C. Daily weight
- D. Vital signs every 4 hours
Correct answer: C
Rationale: Daily weight is the most important data for the nurse to obtain in determining the client's fluid status in this scenario. During febrile episodes, assessing daily weight is crucial as it can indicate fluid retention or loss. While monitoring intake and output is important for assessing fluid balance, daily weight provides a more comprehensive picture of fluid status over time. Skin turgor is more indicative of hydration status than overall fluid status, and vital signs, although essential, do not directly assess fluid status as effectively as daily weight.
2. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?
- A. Reposition the nasal cannula
- B. Lower the oxygen rate
- C. Encourage the client to cough and deep breathe
- D. Monitor the client's oxygen saturation level
Correct answer: B
Rationale: In this scenario, the client with COPD receiving increased oxygen is experiencing oxygen toxicity, leading to lethargy and confusion. Lowering the oxygen rate is the priority action to prevent further harm. Repositioning the nasal cannula, encouraging coughing and deep breathing, and monitoring oxygen saturation are all important interventions, but the immediate concern is to address the oxygen toxicity by lowering the oxygen rate.
3. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?
- A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
- B. Administer a retention enema of Kayexalate.
- C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
- D. Administer a lidocaine bolus IV push.
Correct answer: B
Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.
4. 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.
5. 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.
