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.

A nurse is planning care for a hospitalized toddler. To best maintain the toddler's sense of control and security and ease feelings of helplessness and fear, the nurse should perform which action?
- A. Allow the toddler to play with other children in the nursing unit playroom.
- B. Spend as much time as possible with the toddler.
- C. Allow the toddler to select toys from the nursing unit playroom that can be brought into the toddler's hospital room.
- D. Keep hospital routines as similar as possible to those at home.
Correct Answer: D
Rationale: The best action for the nurse to take to help a hospitalized toddler maintain a sense of control and security and ease feelings of helplessness and fear is to keep hospital routines as similar as possible to those at home. By incorporating the toddler's usual rituals and routines from home into nursing care activities, the nurse can reduce the stress of hospitalization. This approach gives the toddler a sense of familiarity, control, and security, which can alleviate feelings of helplessness and fear. Allowing the toddler to play with other children in the nursing unit playroom and selecting toys are beneficial activities, but maintaining hospital routines similar to those at home is the most effective way to support the toddler's emotional well-being during hospitalization.
A patient reports, "I tore 3 of my 4 Rotator cuff muscles in the past."? Which of the following muscles cannot be considered as possibly being torn?
- A. Teres minor
- B. Teres major
- C. Supraspinatus
- D. Infraspinatus
Correct Answer: B
Rationale: The correct answer is Teres major. The Rotator Cuff consists of Teres Minor, Infraspinatus, Supraspinatus, and Subscapularis muscles, not Teres major. Teres major is not part of the rotator cuff, so it cannot be considered as possibly being torn. The other choices, Teres minor, Supraspinatus, and Infraspinatus, are all part of the Rotator Cuff and could potentially be torn in this patient's case.
A nurse provides instructions to an older adult about measures to prevent heatstroke. Which statement by the client indicates a need for further instruction?
- A. ''I should wear cool, light clothing in warm weather.''
- B. ''I need to wear a hat with a wide brim when I go outdoors.''
- C. ''I need to wear additional antiperspirant and deodorant in warm weather.''
- D. ''I should drink extra fluids during the summer.''
Correct Answer: C
Rationale: As an individual ages, the number of sweat glands decreases, resulting in reduced body odor and decreased evaporative heat loss due to less sweating. The need for antiperspirants and deodorants is reduced in older adults. Therefore, the statement 'I need to wear additional antiperspirant and deodorant in warm weather' indicates a need for further instruction. Older adults should focus on wearing cool, light clothing in warm weather to prevent overheating, wearing a hat with a wide brim when outdoors to protect from the sun's rays, and staying hydrated by drinking extra fluids during the summer. These measures are more effective in preventing heatstroke in older adults compared to using additional antiperspirants and deodorants, which are not necessary.
A nurse is determining the fetal heart rate (FHR) and places the fetoscope on the mother's abdomen to count the FHR. The nurse simultaneously palpates the mother's radial pulse and notes that it is synchronized with the sounds heard through the fetoscope. Which action should the nurse take?
- A. Count the FHR for 60 seconds, ensuring that it is synchronized consistently with the mother's radial pulse.
- B. Move the fetoscope to another area on the mother's abdomen to locate the fetal heart.
- C. Ask the mother to lie still while both the FHR and the radial pulse rate are counted.
- D. Count the FHR for 30 seconds and then count the radial pulse rate of the mother for 30 seconds.
Correct Answer: B
Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.
A nurse is interviewing an older adult while assisting with data collection. Which client comment regarding vision requires immediate discussion with the health care provider?
- A. "If I go from a very bright room to a very dark room, I have some trouble adjusting."
- B. "I have to hold my newspaper farther and farther away from me when I read."
- C. "I have a little trouble telling if my same-colored shirts and blouses actually match; the colors seem the same to me."
- D. "It looks like I have a blank spot in the middle of what I'm trying to see."
Correct Answer: D
Rationale: The correct answer is "It looks like I have a blank spot in the middle of what I'm trying to see." Seeing blank spots in the middle of an object is a sign of central vision loss, which is a symptom of macular degeneration. Macular degeneration is a serious condition that requires immediate discussion with a healthcare provider to prevent further vision loss. Choice A, mentioning difficulty adjusting between bright and dark rooms, is a common issue related to changes in lighting and not a cause for immediate concern. Choice B, having to hold objects farther away when reading, is indicative of presbyopia, a normal age-related change in vision. Choice C, experiencing slight changes in color perception, is also a common age-related change and not an urgent issue that necessitates immediate discussion with a healthcare provider.
