Nokea
A nurse is caring for a client who is 3 hr postoperative and exhibiting signs of hypovolemia. Which of the following findings should the nurse identify as a manifestation of hypovolemia?
- A. Rapid pulse rate
- B. Bradycardia
- C. Hypertension
- D. Peripheral edema
Correct Answer: A
Rationale: The correct answer is A: Rapid pulse rate. Following surgery, hypovolemia can occur due to fluid loss. A rapid pulse rate is a common manifestation of hypovolemia as the body compensates for decreased blood volume by increasing heart rate to maintain perfusion. Bradycardia (B) is unlikely with hypovolemia as the body tries to increase cardiac output. Hypertension (C) is not typical in hypovolemia as blood pressure tends to decrease. Peripheral edema (D) is associated with fluid overload, not hypovolemia.

A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer?
- A. 0.4 mL
- B. 0.5 mL
- C. 0.6 mL
- D. 0.7 mL
Correct Answer: B
Rationale: To calculate the dose of enoxaparin, first convert the client's weight from pounds to kilograms: 154 lb/2.2 = 70 kg. Then, calculate the dose: 0.75 mg/kg x 70 kg = 52.5 mg. Since the concentration is 60 mg/0.6 mL, divide the dose needed by the concentration: 52.5 mg/60 mg x 0.6 mL = 0.5 mL. Therefore, the correct answer is B (0.5 mL). Choice A is incorrect as it is less than the calculated dose. Choice C is incorrect as it is based on the concentration but does not match the calculated dose. Choice D is incorrect as it is higher than the calculated dose.
A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available is potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number.)
- A. 50 mL/hr
- B. 75 mL/hr
- C. 100 mL/hr
- D. 125 mL/hr
Correct Answer: C
Rationale: To calculate the infusion rate, we need to use the formula: (Desired dose ÷ Volume) x 60 minutes. In this case, the desired dose is 10 mEq over 1 hour, and the volume is 100 mL.
So, (10 ÷ 100) x 60 = 6 mL/hr. Therefore, the nurse should set the infusion pump to deliver 100 mL/hr. This ensures the correct administration of potassium chloride over the specified time frame.
Choice A (50 mL/hr) and B (75 mL/hr) are incorrect as they would result in the underdosing of potassium chloride. Choice D (125 mL/hr) is incorrect as it would result in the overdosing of potassium chloride. The correct answer, C (100 mL/hr), ensures the proper administration of the medication within the specified parameters.
A nurse in a long-term care facility is caring for a client who has dementia. Which of the following actions should the nurse take?
- A. Encourage the client to eat independently with utensils.
- B. Provide finger food at mealtime.
- C. Feed the client only pureed foods.
- D. Offer the client fluids only between meals.
Correct Answer: B
Rationale: The correct answer is B: Provide finger food at mealtime. This option is appropriate for a client with dementia as it promotes independence and encourages self-feeding, which can help maintain their dignity and autonomy. Finger foods are easy to handle and reduce the risk of frustration or confusion that may arise from using utensils. Encouraging self-feeding also helps stimulate cognitive function and maintain motor skills.
A: Encouraging the client to eat independently with utensils may be challenging and frustrating for someone with dementia.
C: Feeding the client only pureed foods may not be necessary if the client is able to eat regular food safely.
D: Offering fluids only between meals may lead to dehydration, especially for clients who may forget to ask for fluids when needed.
A nurse is caring for a male client who has a new prescription for cyclosporine following a kidney transplant. Which of the following findings should the nurse identify as an adverse effect of this therapy?
- A. BUN 24 mg/dL
- B. Blood glucose 95 mg/dL
- C. Platelets 250
- D. 000/mm³
- E. Hemoglobin 14 g/Dl
Correct Answer: A
Rationale: The correct answer is A: BUN 24 mg/dL. Cyclosporine, an immunosuppressant medication, can cause nephrotoxicity as an adverse effect. An elevated BUN level indicates impaired kidney function, which can be a consequence of cyclosporine therapy. Blood glucose level (choice B) and platelet count (choice C) are not typically affected by cyclosporine. Hemoglobin level (choice E) is not directly related to cyclosporine therapy. Therefore, the nurse should be vigilant for signs of nephrotoxicity by monitoring the client's BUN level.
A nurse is providing preoperative teaching about stool consistency to a client who will undergo a colectomy with the placement of an ileostomy. Which of the following information about stool consistency should the nurse include in the teaching?
- A. The stool will be firm and well-formed.
- B. The stool will have a high volume of liquid.
- C. The stool will be similar to normal bowel movements.
- D. The stool will be hard and difficult to pass.
Correct Answer: B
Rationale: The correct answer is B: The stool will have a high volume of liquid. Following a colectomy with an ileostomy, the client will have fecal output from the small intestine, resulting in a high volume of liquid stool. This is because the large intestine, responsible for absorbing water and forming solid stool, is bypassed with an ileostomy. Choice A is incorrect because the stool will not be firm and well-formed. Choice C is incorrect because the stool will not be similar to normal bowel movements due to the absence of the large intestine. Choice D is incorrect as the stool will not be hard and difficult to pass.
