1. What is a predisposing factor for cancer of the tongue?

• A. tobacco use
• B. obesity
• C. sun exposure
• D. eating sweets

Correct answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

2. 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.

3. Which of the following lab values is elevated first after a client has a myocardial infarction?

• A. LDH
• B. troponin
• C. CPK
• D. SGOT

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

4. Which of the following devices may be applicable to a bedridden patient to address potential venous insufficiency?

• A. Shear-reducing mattress
• B. Sequential compression devices
• C. Hiking stockings
• D. Non-skid socks

Correct answer: B

Rationale: For a bedridden patient with potential venous insufficiency, sequential compression devices (SCDs) and compression stockings are appropriate choices. SCDs help improve venous return from the lower extremities by applying sequential pressure, aiding circulation. Compression stockings also assist in preventing blood from pooling in the legs by applying pressure to support venous return. Shear-reducing mattresses are not directly related to managing venous insufficiency, as they are designed to reduce friction and shear forces on the skin to prevent pressure ulcers. Non-skid socks are primarily used for fall prevention and have no direct impact on venous insufficiency.

5. A graduate nurse hired to work in a medical unit of a hospital is attending an orientation session. The nurse educator, discussing care maps, asks the graduate nurse whether she understands how a care map is used. Which response indicates understanding?

• A. The care map outlines the day-to-day expected outcomes of care and the outcomes anticipated at discharge
• B. The care map is a plan that is used only by the nurse to provide client care
• C. The care map is a standard plan, rather than an individualized one, that is developed strictly by a nurse and used for a client with a particular diagnosis
• D. The care map is developed by a nurse and identifies nursing diagnoses

Correct answer: A

Rationale: The correct answer is A. A care map, also known as a critical pathway, outlines the day-to-day expected outcomes of care and the outcomes anticipated at discharge or the end of a treatment phase. It includes clinical assessments, treatments, dietary interventions, activity therapies, client education, and discharge planning. While it may identify nursing diagnoses, a care map is developed by all disciplines caring for the client type and is used by the interdisciplinary team, not just the nurse alone. Choice B is incorrect because a care map is not solely for the nurse but for the entire interdisciplinary team. Choice C is incorrect as care maps are individualized plans developed by the interdisciplinary team, not just by a nurse. Choice D is incorrect as a care map is not solely about nursing diagnoses but encompasses a comprehensive plan of care.
