1. How often should a 5-year-old child undergo a dental examination?

A. Every 6 months
B. Whenever a new primary tooth erupts
C. Once a year
D. Every 3 months

Correct answer: A

Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.

2. To identify risk factors associated with the use of an oral contraceptive, which question should the nurse ask a client providing subjective data?

A. Do you normally experience menstrual cramps with your periods?
B. Do you smoke cigarettes?
C. Are you currently dieting?
D. Do you engage in strenuous exercise, such as jogging?

Correct answer: B

Rationale: The correct question the nurse should ask to identify risk factors associated with the use of an oral contraceptive is whether the client smokes cigarettes. Oral contraceptives are associated with an increased risk of thromboembolic phenomena, particularly when combined with other risk factors like smoking and a history of thrombosis. Other risk factors include hypertension, cerebrovascular disease, coronary artery disease, and postoperative thrombosis risk. Choices A, C, and D are not directly related to the increased risks associated with oral contraceptive use. Menstrual cramps, dieting, and strenuous exercise are not significant risk factors for thromboembolic events.

3. What effect can medication bound to protein have?

A. reduced drug availability
B. limited distribution of the drug to receptor sites
C. less availability to produce desired medicinal effects
D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

4. Which of the following vaccines contains a live virus?

A. varicella
B. IPV
C. DTaP
D. hepatitis B

Correct answer: A

Rationale: The correct answer is varicella. Varicella vaccine contains a live, weakened form of the varicella-zoster virus. Choice B, IPV (inactivated poliovirus vaccine), is an inactivated vaccine, not a live virus vaccine. Choices C and D, DTaP (diphtheria, tetanus, and acellular pertussis vaccine) and hepatitis B vaccine, respectively, do not contain live viruses. Varicella is the only live virus vaccine among the options.

5. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

A. 0.9% sodium chloride
B. 5% dextrose in water solution
C. Sterile water
D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.
