1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
2. While changing the pressure ulcer dressing of a client who is immobile, the nurse notes that the boundary edges of the wound have increased. Before reporting this finding to the healthcare provider, the nurse should review which of the client’s serum laboratory values?
- A. Potassium
- B. Platelets
- C. Creatinine
- D. Albumin
Correct answer: D
Rationale: The correct answer is D: Albumin. Reviewing albumin levels is crucial in this situation because low albumin levels can impact wound healing and contribute to increased wound edges. Potassium (choice A) is not directly related to wound healing or wound edges. Platelets (choice B) are more related to blood clotting than wound healing. Creatinine (choice C) is related to kidney function, not specifically to wound healing or wound edges.
3. A male client with hypertension, who received new antihypertensive prescriptions at his last visit, returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him 'feel bad.' In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?
- A. Feed the client a snack
- B. Empty the urinary drainage bag
- C. Offer the client oral fluids
- D. Stroke secondary to hemorrhage
Correct answer: D
Rationale: Elevated blood pressure, if left uncontrolled, significantly increases the risk of stroke secondary to hemorrhage and other cardiovascular events. This condition can lead to serious complications due to the increased pressure on the blood vessels in the brain. Choices A, B, and C are unrelated to the potential pathophysiological consequences of uncontrolled hypertension and are not the primary concern in this scenario.
4. A male client with schizophrenia tells the nurse that the hospital has installed cameras that watch him and listening devices that record what everyone says. Which nursing problem should the nurse document for this client?
- A. Noncompliance with medication related to thought broadcasting
- B. Situational self-esteem disturbance secondary to schizophrenia
- C. Disturbed sensory perception related to auditory hallucinations
- D. Impaired environmental interpretation related to paranoid delusions
Correct answer: D
Rationale: The correct answer is D: Impaired environmental interpretation related to paranoid delusions. The client's belief about cameras watching and recording him is a manifestation of paranoid delusions, indicating a misinterpretation of the environment. Choice A is incorrect because thought broadcasting is not directly related to the client's belief about surveillance equipment. Choice B is incorrect as self-esteem disturbance is not the primary issue presented. Choice C is also incorrect as the client is not experiencing auditory hallucinations but rather paranoid delusions about surveillance.
5. When should the nurse conduct an Allen’s test?
- A. When obtaining pulmonary artery pressures
- B. To assess for the presence of a deep vein thrombus in the leg
- C. Just before arterial blood gases are drawn peripherally
- D. Prior to attempting a cardiac output calculation
Correct answer: C
Rationale: The correct time to conduct an Allen’s test is just before arterial blood gases are drawn peripherally. This test is performed to assess the adequacy of collateral circulation in the hand before obtaining arterial blood gases. Choice A is incorrect because an Allen’s test is not specifically done when obtaining pulmonary artery pressures. Choice B is incorrect because an Allen’s test is not used to assess deep vein thrombosis. Choice D is incorrect because an Allen’s test is not done specifically before attempting a cardiac output calculation.
