Correct Answer: A

Rationale: The correct answer is A. The Institute for Safe Medication Practices recommends using the complete medication name magnesium sulfate when documenting medications to prevent misinterpretation. Choice B is incorrect because spaces should be maintained between the numerical dose and unit of measure for clarity. Choice C is incorrect as the standard notation for insulin dosage is in units, not using the letter U. Choice D is incorrect as the abbreviation for subcutaneous injection is commonly written as 'subcut' or 'subcutaneous,' not as SC.

Correct Answer: A

Rationale: Pharyngeal diphtheria is primarily spread through droplet transmission, which occurs when an infected person coughs, sneezes, or talks, releasing respiratory droplets containing the bacteria. Therefore, the correct precaution for caring for a client with pharyngeal diphtheria is droplet precautions. Droplet precautions help prevent the transmission of respiratory pathogens over short distances via respiratory droplets. Contact precautions are used for diseases spread through direct or indirect contact with the patient or their environment. Airborne precautions are used for diseases that spread through small droplets suspended in the air. Standard precautions are basic infection prevention practices applying to all patient care.

Correct Answer: B

Rationale: The correct term the healthcare provider will use when reporting the extremely bad breath of the unconscious patient to the oncoming shift is 'Halitosis' (Choice B). Halitosis specifically refers to bad breath. Cheilitis (Choice A) is inflammation of the lips, not related to bad breath. Glossitis (Choice C) is inflammation of the tongue, not directly associated with bad breath. Dental caries (Choice D) are cavities in the teeth, which can contribute to bad breath but are not the term used to describe bad breath itself.

Correct Answer: C

Rationale: In this scenario, the nurse should instruct the client to take deep rhythmic breaths as a non-pharmacological pain management method. Deep breathing can help the client relax, reduce stress, and manage pain effectively. Applying heat or ice for prolonged periods can lead to tissue damage. Removing distractions can be helpful for promoting relaxation but may not directly address the pain itself.

Correct Answer: D

Rationale: The correct answer is to check the IV tubing for obstruction. The first step in the nursing process is assessment. By checking the IV tubing for obstruction, the nurse can assess and potentially correct any issues affecting the flow rate. This action may help to ensure that the prescribed infusion rate is maintained. Repositioning the client is not the priority at this stage as the issue seems related to the IV tubing. Documenting the intake or requesting a new prescription are not immediate actions needed to address the current situation with the IV fluid flow.
