Nursing Elites

1. The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?

• A. 0.35 ml
• B. 0.40 ml
• C. 0.50 ml
• D. 0.45 ml

Correct answer: B

Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.

2. Which needle should the nurse use to administer intravenous fluids (IV) via a client's implanted port?

• A. The one with the clamp and no needle
• B. A butterfly needle
• C. A non-coring (Huber) needle
• D. A standard hypodermic needle

Correct answer: C

Rationale: The correct needle to use for administering intravenous fluids via an implanted port is a non-coring (Huber) needle. This type of needle is specifically designed to access implanted ports without coring the septum, which helps prevent damage. Choice A, the one with the clamp and no needle, is incorrect as it does not describe a needle suitable for accessing an implanted port. Choice B, a butterfly needle, is not typically used for accessing implanted ports. Choice D, a standard hypodermic needle, is not ideal for accessing ports as it can damage the septum.

3. The mother of an adolescent tells the clinic nurse, 'My son has athlete's foot. I have been applying triple antibiotic ointment for two days, but there has been no improvement.' What instruction should the nurse provide?

• A. Antibiotics take two weeks to become effective against fungal infections like athlete's foot.
• B. Continue using the ointment for a full week, even after the symptoms disappear.
• C. Applying too much ointment can reduce its effectiveness. Apply a thin layer to prevent maceration.
• D. Stop using the ointment and encourage complete drying of the feet and wearing clean socks.

Correct answer: D

Rationale: The correct answer is D. Athlete's foot (tinea pedis) is a fungal infection, not a bacterial infection that would respond to antibiotics. The primary management involves keeping the feet well-ventilated, dry after bathing, and wearing clean socks to prevent moisture buildup, which promotes fungal growth. Using an antibiotic ointment like triple antibiotic ointment is not effective for treating athlete's foot. Therefore, the nurse should advise the mother to stop using the antibiotic ointment and focus on promoting proper foot hygiene to manage the fungal infection. Choices A, B, and C are incorrect as they do not address the fungal nature of athlete's foot and the ineffectiveness of antibiotic ointments in its treatment.

4. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which clinical finding is most concerning?

• A. Headache
• B. Prothrombin time (PT) of 15 seconds
• C. Elevated liver enzymes
• D. Peripheral edema

Correct answer: A

Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.
