1. When preparing to insert an indwelling urinary catheter, the nurse applies sterile gloves and then tests the catheter balloon for patency. What action should the nurse implement next?
- A. Place a sterile drape under the client's buttocks.
- B. Instruct the client to inhale and then exhale slowly.
- C. Discard the gloves and apply new sterile gloves.
- D. Apply a sterile lubricant to the end of the catheter.
Correct answer: D
Rationale: After testing the catheter balloon for patency, the nurse should proceed to apply a sterile lubricant to the end of the catheter. This lubrication helps facilitate the insertion of the catheter smoothly. Placing a sterile drape under the client's buttocks should have been done prior to this step. Discarding the gloves and applying new sterile gloves is not necessary at this point in the procedure. Instructing the client to inhale and exhale slowly is not part of the immediate steps for inserting an indwelling urinary catheter.
2. The liver is an organ responsible for detoxifying the body of many harmful substances. You might expect the liver to contain a high amount of which of the following?
- A. Rough endoplasmic reticulum
- B. Smooth endoplasmic reticulum
- C. Mitochondria
- D. Lysosomes
Correct answer: B
Rationale: The correct answer is B: Smooth endoplasmic reticulum. The liver contains a high amount of smooth endoplasmic reticulum because it plays a significant role in detoxification processes, such as the synthesis of detoxifying enzymes and lipids. Choice A (Rough endoplasmic reticulum) is incorrect because the rough endoplasmic reticulum is more involved in protein synthesis and processing. Choice C (Mitochondria) is incorrect as mitochondria are primarily responsible for energy production. Choice D (Lysosomes) is incorrect because lysosomes are organelles involved in intracellular digestion and waste removal, not specifically related to detoxification.
3. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?
- A. 50 ml/hour
- B. 25 ml/hour
- C. 75 ml/hour
- D. 100 ml/hour
Correct answer: C
Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.
4. The nurse is assessing a client with left-sided heart failure. Which finding is most concerning?
- A. Jugular venous distention
- B. Crackles in the lungs
- C. Shortness of breath
- D. Peripheral edema
Correct answer: C
Rationale: Shortness of breath is most concerning in a client with left-sided heart failure as it indicates pulmonary congestion, requiring immediate intervention. Jugular venous distention (Choice A) is a sign of increased central venous pressure but is not as concerning as pulmonary congestion. Crackles in the lungs (Choice B) are common in heart failure due to fluid accumulation but are not as immediately concerning as severe shortness of breath. Peripheral edema (Choice D) is a manifestation of fluid retention in the body but is less indicative of acute pulmonary distress compared to shortness of breath.
5. A nurse at a provider's office is reinforcing teaching with a client who is being treated with chemotherapy and is losing weight. Which of the following instructions should the nurse give to increase the client's caloric intake? (Select one that doesn't apply).
- A. Top yogurt with granola.
- B. Use honey on toast.
- C. Use milk instead of water in recipes.
- D. Increase fluids during meals.
Correct answer: D
Rationale: Increasing fluids during meals does not directly contribute to increasing caloric intake. Topping yogurt with granola, using honey on toast, and using milk instead of water in recipes are effective ways to boost caloric intake. While adequate fluid intake is important for hydration and overall health, it does not address the specific need to increase caloric intake in this scenario.
