1. A condition that is conducive to the development of dental caries is said to be _____.
- A. periodontal
- B. cariogenic
- C. gingival
- D. bacteriophilic
Correct answer: B
Rationale: A condition that is conducive to the development of dental caries is described as cariogenic. Cariogenic refers to foods or conditions that promote the development of dental caries by providing an environment for bacteria to thrive and produce acids that erode tooth enamel. Choice A, periodontal, is incorrect as it relates to the supporting structures of the teeth rather than the development of dental caries. Choice C, gingival, is also incorrect as it pertains to the gums rather than the causation of dental caries. Choice D, bacteriophilic, is not the term commonly used to describe conditions that lead to dental caries, making it an incorrect choice.
2. Fee-for-service care is best characterized by which statement:
- A. Fees are scaled based on the patient’s ability to pay and are capped.
- B. Fees reflect the fair market value of health care services being provided.
- C. Adequate fee schedules enable hospitals and clinics to function properly.
- D. Fees are not uniform throughout most states as they are fairly unregulated.
Correct answer: D
Rationale: Fee-for-service care is a payment model where providers are paid for each service performed, leading to non-uniform fees that vary by service and provider. This system is not highly regulated, resulting in differing fee structures across states and regions. Therefore, the statement that 'Fees are not uniform throughout most states as they are fairly unregulated' best characterizes fee-for-service care.
3. A nurse is assessing a client who has a heart rate of 40/min. The client is diaphoretic and has chest pain. Which of the following medications should the nurse plan to administer?
- A. Lidocaine
- B. Adenosine
- C. Atropine
- D. Verapamil
Correct answer: C
Rationale: The correct answer is C: Atropine. The client's presentation of bradycardia, diaphoresis, and chest pain indicates reduced cardiac output, requiring intervention to increase the heart rate. Atropine is used to treat bradycardia by blocking cardiac muscarinic receptors, thus inhibiting the parasympathetic nervous system. Lidocaine (Choice A) is used for ventricular arrhythmias, not bradycardia. Adenosine (Choice B) is used for supraventricular tachycardia, not bradycardia. Verapamil (Choice D) is a calcium channel blocker used for certain arrhythmias and hypertension, but not for increasing heart rate in bradycardia.
4. During pregnancy, a woman is in a relationship with a male who routinely abuses her. Her unborn child may engage in high-risk behavior as a teen as a result of:
- A. Maternal stress
- B. Parental nurturing
- C. Appropriate stress responses in the brain
- D. Memories of the abuse
Correct answer: A
Rationale: Maternal stress during pregnancy can have long-term effects on the child's behavior and stress responses. Research shows that exposure to high levels of stress hormones in the womb can influence the developing fetal brain and the child's future behavior, potentially leading to high-risk behaviors during adolescence.
5. A nurse is preparing to insert an indwelling urinary catheter for a male client. Which of the following actions should the nurse take?
- A. Insert the catheter until urine flows, then advance 2.5 to 5 cm (1 to 2 in) further.
- B. Advance the catheter 7.5 to 10 cm (3 to 4 in) after urine begins to flow.
- C. Advance the catheter 17 to 22.5 cm (7 to 9 in) after urine begins to flow.
- D. Advance the catheter 5 to 7.5 cm (2 to 3 in) after urine begins to flow.
Correct answer: C
Rationale: When inserting an indwelling urinary catheter for a male client, it is crucial to advance the catheter 17 to 22.5 cm after urine begins to flow. This helps ensure proper placement in the male urethra, which is longer compared to females. Choice A is incorrect as advancing only 2.5 to 5 cm would not reach the correct placement in male clients. Choice B is incorrect as advancing 7.5 to 10 cm is insufficient to reach the appropriate location in male clients. Choice D is also incorrect as advancing 5 to 7.5 cm would likely not reach the desired placement in male clients.
