The staff nurse in a regional hospital is aware that a dose of parenteral ampicillin must be administered within how many hours after it has been mixed?
- A. 1 hour
- B. 4 hours
- C. 2 hours
- D. 8 hours
Correct Answer: B
Rationale: The correct answer is B (4 hours) because parenteral ampicillin should be administered within 1 hour of mixing. This is crucial to ensure efficacy and prevent bacterial growth in the solution. Choice A (1 hour) is incorrect because it does not allow enough time for administration after mixing. Choice C (2 hours) is also incorrect as it exceeds the recommended time limit. Choice D (8 hours) is incorrect as it exceeds the safe window for administration post-mixing, increasing the risk of bacterial contamination and reduced effectiveness. Thus, the optimal timeframe for administering parenteral ampicillin after mixing is within 4 hours to maintain its therapeutic benefits.

A nurse is developing a care plan for a patient with a pelvic fracture on bed rest. Which goal statement is realistic for the nurse to assign to this patient?
- A. Patient will increase activity level this shift.
- B. Patient will turn side to back to side with assistance every 2 hours.
- C. Patient will use the walker correctly to ambulate to the bathroom as needed.
- D. Patient will use a sliding board correctly to transfer to the bedside commode as needed.
Correct Answer: C
Rationale: The correct answer is C because it is a realistic goal for a patient with a pelvic fracture on bed rest. The patient needs to use a walker correctly to ambulate safely to the bathroom, which promotes mobility and independence while ensuring safety. This goal is specific, measurable, achievable, relevant, and time-bound.
Choice A is incorrect because increasing activity level may not be safe or feasible for a patient with a pelvic fracture. Choice B is incorrect as turning every 2 hours may not be necessary or practical for this patient. Choice D is incorrect as using a sliding board may not be appropriate or necessary for someone with a pelvic fracture.
The nurse is caring for a client who’s hypoglycemic. This client will have a blood glucose level:
- A. Below 70mg/dl
- B. Between 120 and 180mg/dl
- C. Between 70 and 120mg/dl
- D. Over 180mg/dl
Correct Answer: A
Rationale: The correct answer is A: Below 70mg/dl. Hypoglycemia is defined as a blood glucose level below 70mg/dl. Symptoms of hypoglycemia include confusion, shakiness, and sweating. Treating hypoglycemia involves administering fast-acting carbohydrates. Choices B, C, and D are incorrect because they describe blood glucose levels that are within the normal or hyperglycemic range, which are not indicative of hypoglycemia. It is essential for the nurse to recognize and promptly address hypoglycemia to prevent serious complications.
A nurse determines that the patient’s condition has improved and has met expected outcomes. Which step of the nursing process is the nurse exhibiting?
- A. Assessment
- B. Planning
- C. Implementation NursingStoreRN
- D. Evaluation
Correct Answer: D
Rationale: The correct answer is D: Evaluation. In the nursing process, evaluation involves determining if the patient's condition has improved and if the expected outcomes have been met. The nurse assesses the patient's progress, compares it to the expected outcomes set during planning, and determines the effectiveness of the interventions implemented. This step ensures that the care provided is meeting the patient's needs and helps in making any necessary adjustments to the care plan.
Incorrect choices:
A: Assessment - This step involves gathering information about the patient's condition and needs at the beginning of the nursing process.
B: Planning - Involves setting goals and developing a plan of care based on the assessment data.
C: Implementation - Involves carrying out the interventions outlined in the care plan to meet the patient's goals.
A patient expresses fear of going home and being alone. Vital signs are stable and the incision is nearly completely healed. What can the nurse infer from the subjective data?
- A. The patient can now perform the dressing changes without help.
- B. The patient can begin retaking all of the previous medications.
- C. The patient is apprehensive about discharge.
- D. The patient’s surgery was not successful.
Correct Answer: C
Rationale: The correct answer is C: The patient is apprehensive about discharge. The rationale is that the patient's fear of going home and being alone indicates anxiety about leaving the hospital setting. This subjective data suggests that the patient may not feel ready for discharge despite stable vital signs and nearly healed incision. Choices A and B are incorrect because they assume the patient's readiness for self-care without considering emotional factors. Choice D is incorrect as there is no evidence provided that the surgery was unsuccessful.
A 34 year old client is diagnosed with AIDS. His pharmacologic management includes zidovudine (AZT). During a home visit, the client states, “I don’t understand how this medication works. Will it stop the infection?” What is the nurse’s best response?
- A. The medication helps to slow the disease process, but it won’t cure or stop it totally
- B. The medication blocks reverse transcriptase, the enzyme required fro HIV replication
- C. Don’t you know? There aren’t medication to stop or cure HIV
- D. No. it won’t stop the infection. In fact, sometimes the HIV can become immune to the drug itself
Correct Answer: B
Rationale: The correct answer is B. The nurse should explain that zidovudine (AZT) works by blocking reverse transcriptase, the enzyme necessary for HIV replication. This is the key mechanism of action for AZT in managing HIV.
Choice A is incorrect because it provides a partial truth - it does slow the disease process but does not provide the mechanism of action. Choice C is incorrect as it provides incorrect information that there are no medications to stop or cure HIV, which is not true. Choice D is incorrect as it provides misleading information about the drug becoming immune to HIV, which is not the primary concern in this context.
