Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?
- A. skin
- B. adipose tissue
- C. skeletal muscle
- D. myocardium
Correct Answer: D
Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.

What is one of the main goals of Healthy People 2010?
- A. reduction of health care costs
- B. elimination of health disparities
- C. investigation of substance abuse
- D. determination of an acceptable morbidity rate
Correct Answer: C
Rationale: The main goal of Healthy People 2010 is the elimination of health disparities among the U.S. population. This initiative outlines specific objectives to improve the overall health of Americans by addressing disparities in health outcomes. Choice A, reduction of health care costs, is not the primary goal of Healthy People 2010, although it may be a beneficial outcome. Choice C, investigation of substance abuse, is not a main goal of Healthy People 2010; while substance abuse may be a factor in health disparities, the primary focus is on broader disparities. Choice D, determination of an acceptable morbidity rate, is not the main focus of Healthy People 2010; instead, it aims to address health disparities in different population groups.
A 2-year-old child diagnosed with HIV comes to a clinic for immunizations. Which of the following vaccines should the healthcare provider expect to administer in addition to the scheduled vaccines?
- A. pneumococcal vaccine
- B. hepatitis A vaccine
- C. Lyme disease vaccine
- D. typhoid vaccine
Correct Answer: A
Rationale: The correct answer is the pneumococcal vaccine. Children with HIV are at increased risk of pneumococcal infections, so the pneumococcal vaccine is recommended as a supplemental vaccine for them. The hepatitis A vaccine is not routinely given to HIV-positive children unless they have other risk factors for hepatitis A. Lyme disease vaccine is for individuals at risk for Lyme disease, not routinely recommended for a 2-year-old. Typhoid vaccine is typically given to individuals traveling to endemic areas or working in settings with potential exposure to Salmonella typhi, not a routine vaccine for a 2-year-old with HIV.
The parents of an adolescent tell the school nurse that they are frustrated because their daughter has become self-centered, lazy, and irresponsible. The nurse should provide which response to the parents?
- A. That this is normal behavior for an adolescent
- B. That their daughter's behavior may be a part of adolescent development
- C. That this behavior could be a phase as the adolescent explores identity
- D. To restrict any social privileges until the behavior stops
Correct Answer: A
Rationale: During adolescence, identity formation is a significant developmental task. Adolescents may appear self-centered, lazy, or irresponsible as they focus on themselves and explore their identity. Erikson describes this phase as identity formation versus role confusion. It is common for frustrated parents to perceive teenagers this way. The adolescent needs time to introspect and develop a sense of self. Suggesting that the behavior requires a child psychologist is premature and not supported by normal adolescent development. Blaming the behavior on parental spoiling is also inaccurate and unhelpful. Restricting social privileges can lead to resentment and rebellion, rather than addressing the root of the behavior.
A nurse is assisting with developing a plan of care for an older client to help maintain an adequate sleep pattern. Which action should the nurse suggest be included in the plan?
- A. Encouraging bedtime reading or listening to music
- B. Encouraging at least one daytime nap
- C. Discouraging the use of a nightlight at bedtime
- D. Discouraging social interaction, particularly at bedtime
Correct Answer: A
Rationale: To help maintain an adequate sleep pattern in older clients, it is essential to include activities that promote relaxation and a conducive sleep environment. Encouraging bedtime reading or listening to music can help the client unwind and prepare for sleep. Daytime naps should be discouraged to ensure a better nighttime sleep. Social interaction, especially positive interactions, can be beneficial and should not be discouraged. The use of a nightlight can create a safe and comfortable environment for the client, so it should not be discouraged unless specifically contraindicated.
A nurse auscultating the fetal heart rate (FHR) of a pregnant client in the first trimester of pregnancy notes that the FHR is 160 beats/min. With this information, what should be the nurse's next action?
- A. Notify the healthcare provider of the finding.
- B. Document the findings.
- C. Tell the client that the FHR is faster than normal but that it is nothing to be concerned about at this time.
- D. Wait 15 minutes and then recheck the FHR.
Correct Answer: B
Rationale: An FHR of 160 beats/min in the first trimester of pregnancy is within the normal range, which is generally 120 to 160 beats/min. The appropriate action for the nurse in this situation is to document the findings. There is no need to notify the healthcare provider as this is a normal finding. Informing the client that the FHR is faster than normal may cause unnecessary anxiety, as it falls within the expected range. Waiting to recheck the FHR is not necessary since the rate is already within the normal range.
