Nursing Elites

1. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

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.

2. Nail and foot care are essential in meeting the basic hygiene needs of clients. Important assessments by the nurse in this area include:

• A. a full-body assessment is not specific to nail and foot care.
• B. the essential lab work of the client is not related to nail and foot assessments.
• C. the nail beds and the tissue surrounding the nails.
• D. foot corns and calluses only neglect other important aspects of nail and foot care.

Correct answer: C

Rationale: The correct answer is to assess the nail beds and the tissue surrounding the nails. This assessment is crucial to identify abnormal discoloration, lesions, paronychia, dryness, breaks in the skin, pressure areas, or any other unusual appearances. Choice A is incorrect as a full-body assessment is broader and not specific to nail and foot care. Choice B is incorrect as lab work is not directly related to nail and foot assessments. Choice D is incorrect as it focuses only on foot corns and calluses, neglecting other important aspects of nail and foot care.

3. When the healthcare provider is determining the appropriate size of a nasopharyngeal airway to insert, which body part should be measured on the client?

• A. corner of the mouth to tragus of the ear
• B. corner of the eye to top of the ear
• C. tip of the chin to the sternum
• D. tip of the nose to the earlobe

Correct answer: D

Rationale: A nasopharyngeal airway is measured from the tip of the nose to the earlobe. This measurement ensures that the airway is of the correct length to reach the nasopharynx without being too long or too short. Choices A, B, and C are incorrect as they do not provide the appropriate measurement for selecting the correct size of a nasopharyngeal airway. The distance from the corner of the mouth to the tragus of the ear (Choice A) is used to measure for an oropharyngeal airway, not a nasopharyngeal airway. Similarly, the other choices (B and C) do not correlate with the correct measurement of a nasopharyngeal airway.

4. When providing perineal care to a female client, how should the nurse perform the procedure?

• A. with gloves, washing the perineal area from front to back
• B. without gloves, having the client perform all care
• C. with gloves, washing the perineal area from back to front
• D. without gloves, pouring water from a sterile bottle

Correct answer: A

Rationale: When providing perineal care to a female client, the nurse should wear gloves and wash the perineal area from front to back. This technique helps prevent the introduction of E. coli and other bacteria into the urethra, reducing the risk of urinary tract infections. Washing from back to front can introduce bacteria from the anal area to the urethra, leading to infections. Performing the procedure without gloves or having the client perform all care does not adhere to infection control practices. Pouring water from a sterile bottle alone may not ensure proper cleansing and infection prevention. Therefore, choices B, C, and D are incorrect as they do not follow proper perineal care guidelines.

5. The nurse has completed client teaching about introducing solid foods to an infant. To evaluate teaching, the nurse asks the mother to identify an appropriate first solid food. Which of the following is an appropriate response?

• A. pureed canned squash
• B. pureed apples
• C. yogurt
• D. infant rice cereal

Correct answer: D

Rationale: The correct answer is infant rice cereal. Single-grain infant cereals are recommended as the first solid food because they are easily digestible and have added iron content. Choice C, yogurt, is incorrect because yogurt is a milk product and should be delayed until the child is 12 months old due to the risk of milk allergy. Choices A and B are incorrect because fruits and vegetables are typically introduced after cereals to help the infant get accustomed to solid foods gradually.
