Correct Answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

Correct Answer: C

Rationale: The correct answer is, ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.'' This statement indicates a need for further instructions as the distance between the slats should be no more than 2⅜ inches to prevent entrapment of the infant's head and body, not 4 inches. Allowing a larger gap can pose a risk of entrapment or injury to the infant. Keeping large toys out of the crib is essential to prevent the infant from using them to climb out, which could result in serious injuries. Ensuring the drop side of the crib is impossible for the infant to release is crucial to prevent falls and injuries. Additionally, maintaining wood surfaces on the crib free of splinters, cracks, and lead-based paint is vital for the infant's safety and well-being.

Correct Answer: C

Rationale: The correct action is to immediately discontinue the use of the IVAC pump and obtain a replacement because the frayed cord poses a safety risk to the client. Continuing to use the pump with visible wiring could lead to electric shock or other serious harm to the client. Notifying maintenance to come and check the pump immediately (Choice A) may cause unnecessary delays in ensuring the client's safety. Continuing with the administration of the antibiotic and filling out an equipment maintenance request (Choice B) is unsafe as it ignores the immediate danger. Tagging the equipment for maintenance (Choice D) does not address the urgent need to protect the client from harm.

Correct Answer: A

Rationale: Isolation techniques are used to prevent or limit the spread of infection. Special handling of articles and linens soiled by any body fluid is essential. Linens should be placed in impervious bags before being removed from the client's bedside to prevent exposure of personnel and contamination of the environment. Double-bagging is required if the outside of the bag becomes contaminated. This practice ensures that potentially infectious materials are properly contained and disposed of. Choices B, C, and D are incorrect because the focus in this scenario is on proper handling and disposal of soiled linens to prevent the spread of infection, not on serving meals, psychological effects of isolation, or the use of paper trays and plastic utensils.

Correct Answer: B

Rationale: Celiac disease, also known as celiac sprue, is a malabsorption disorder affecting the small intestine due to a problem with ingesting gluten, a protein found in wheat, rye, oats, and barley. Therefore, oats or barley cereal would present a problem for a client with Celiac Disease as they contain gluten. Fresh vegetables, butter, coffee, and tea, on the other hand, do not contain gluten and should not pose any issues for individuals with this disorder. Therefore, the correct answer is oats or barley cereal. Choices A, C, and D are not problematic for clients with Celiac Disease as they are gluten-free.
