1. High uric acid levels can develop in clients who are receiving chemotherapy. This can be caused by:
- A. the inability of the kidneys to excrete the drug metabolites.
- B. rapid cell catabolism.
- C. toxic effects of the prophylactic antibiotics that are given concurrently.
- D. the altered blood pH from the acidic nature of the drugs.
Correct answer: B
Rationale: The correct answer is 'rapid cell catabolism.' During chemotherapy, rapid cell destruction occurs, leading to an increase in uric acid levels as a byproduct of cell breakdown. High uric acid levels are primarily a result of the rapid breakdown of cells during chemotherapy, not due to the kidneys' inability to excrete drug metabolites (Choice A). The prophylactic antibiotics given concurrently do not directly cause high uric acid levels (Choice C). The altered blood pH from the acidic nature of the drugs (Choice D) is not a direct cause of elevated uric acid levels; the main mechanism is the rapid cell catabolism that occurs during chemotherapy.
2. Which of the following procedures describes an opening between the colon and abdominal wall?
- A. ileostomy
- B. jejunostomy
- C. colostomy
- D. cecostomy
Correct answer: C
Rationale: A colostomy is an opening between the colon and abdominal wall. An ileostomy is an opening between the ileum and abdominal wall, not the colon. Jejunostomy is an opening between the jejunum and abdominal wall, and cecostomy is an opening into the cecum. The term 'colostomy' specifically refers to the surgical procedure where a part of the colon is brought through the abdominal wall to create a stoma, allowing feces to leave the body. Therefore, the correct answer is colostomy as it accurately describes the opening between the colon and the abdominal wall, distinct from the other options.
3. Signs of impaired breathing in infants and children include all of the following except:
- A. nasal flaring
- B. grunting
- C. seesaw breathing
- D. quivering lips
Correct answer: D
Rationale: Signs of impaired breathing in infants and children can manifest in various ways. Nasal flaring, grunting, and seesaw breathing are all indicative of respiratory distress in pediatric patients. Nasal flaring is the widening of the nostrils with breathing effort, grunting is a sound made during exhalation to try to keep the airways open, and seesaw breathing involves the chest moving in the opposite direction of the abdomen. However, quivering lips are not typically associated with impaired breathing in this context. Lip quivering is a distracter and not a common sign of respiratory distress in infants and children. Therefore, the correct answer is 'quivering lips.'
4. Which physiologic mechanism best describes the function of the sodium-potassium pump?
- A. active transport
- B. diffusion
- C. filtration
- D. osmosis
Correct answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
5. Which of the following can certain foods like broccoli, oranges, dark greens, and dark yellow vegetables help improve?
- A. Vitamin intake
- B. Body functions
- C. Defense mechanisms
- D. Disease cure
Correct answer: C
Rationale: Certain foods like broccoli, oranges, dark greens, and dark yellow vegetables can help improve defense mechanisms by enhancing the immune system and overall health. While these foods can boost defense mechanisms, they are not a cure for diseases, do not balance body functions, and are not intended to solely supplement vitamin intake, which may be necessary in some cases. Therefore, the correct answer is defense mechanisms as these foods strengthen the body's ability to fight off illnesses and maintain health.
