Correct Answer: D

Rationale: The correct answer is D: Replace sharps containers when they are 3/4 full. This instruction is crucial in preventing puncture injuries as overfilling sharps containers can increase the risk of accidental needle sticks. By replacing the containers when they are 3/4 full, it ensures that there is enough space to safely dispose of needles and other sharp objects without risking spills or injuries.

Explanation of other choices:
A: Breaking needles on syringes before disposal is unsafe as it can increase the risk of needle stick injuries.
B: Using two hands to recap a needle is dangerous and not recommended as it can lead to accidental needle sticks.
C: Disposing of used razors in wastebaskets is improper as they should be disposed of in puncture-proof containers.
Summary: Option D is the correct choice as it emphasizes safe disposal practices to prevent puncture injuries, while the other options promote unsafe practices that can increase the risk of needle stick injuries.

Correct Answer: A

Rationale: The correct answer is A: Apply pressure to the client’s nasolacrimal duct after instillation. This action helps prevent systemic absorption of the medication and decreases the risk of side effects. By gently pressing on the nasolacrimal duct, the nurse can reduce the systemic absorption of the medication and promote its local effects. This technique is crucial for ophthalmic medications to work effectively and minimize adverse reactions.

Choice B is incorrect because cleaning the eye from outer to inner canthus can introduce contaminants into the eye, increasing the risk of infection.
Choice C is incorrect as tightly squeezing the eyes shut can also lead to systemic absorption of the medication.
Choice D is incorrect as instilling the medication directly onto the cornea can be harmful and may not distribute the medication effectively.

Correct Answer: A,C,D

Rationale: The correct answer is A, C, and D. Fluid overload leads to increased blood pressure due to the increased volume of fluid in the vascular system. Increased respiratory rate occurs as the body tries to compensate for the excess fluid by increasing oxygen intake. Increased heart rate is a response to the increased workload on the heart to pump the excess fluid. Increased hematocrit and temperature are not typically associated with fluid overload. Hematocrit may actually be decreased due to hemodilution, and temperature is usually unaffected unless there is an underlying infection.

Correct Answer: 10

Rationale: The correct answer is 10 tablets.
To calculate, you divide the total dose needed (5 mg) by the dose per tablet (0.5 mg). 5 mg ÷ 0.5 mg = 10 tablets. The nurse should administer 10 tablets of digoxin to achieve the desired 5 mg dose. Other choices are incorrect because they do not result in the correct dosage amount required for the client.

Correct Answer: D

Rationale: The correct answer is D: Rub hand sanitizer around rings on fingers. This is important because rings can harbor bacteria and viruses, and by rubbing hand sanitizer around them, the nurse ensures that all surfaces of the hands, including under the rings, are effectively sanitized. This action helps prevent the transmission of pathogens.

A: Using hot water to rinse hand sanitizer off is unnecessary and can actually be harmful as it can cause skin irritation.
B: Drying hands with a reusable towel is not recommended as it can harbor germs and compromise hand hygiene.
C: Rubbing hands together for 20 seconds is a good practice, but the specific action related to rings is more crucial.
E, F, G: No information provided.
