The lungs regulate acid-base balance b₃y⻠all of the following except:
- A. Excreting HCO into the blood
- B. Controlling carbon dioxide levels
- C. Slowing ventilation
- D. Increasing ventilation
Correct Answer: C
Rationale: The lungs help regulate acid-base balance primarily by controlling carbon dioxide levels through ventilation. When carbon dioxide levels increase in the blood, the lungs increase ventilation to exhale more carbon dioxide and maintain the acid-base balance. Slowing ventilation (Option C) would not help in regulating the acid-base balance as it would lead to a buildup of carbon dioxide in the blood, causing respiratory acidosis. Excreting HCO into the blood (Option A) helps maintain acid-base balance by regulating bicarbonate levels, and increasing ventilation (Option D) is the mechanism through which the lungs primarily adjust acid-base balance.

Which statement is true about smoking in adolescence?
- A. Smoking is related to other high-risk behaviors.
- B. Smoking will not continue unless peer pressure continues.
- C. Smoking is less common when the adolescent's parent(s) smokes.
- D. Smoking among adolescents is becoming more prevalent.
Correct Answer: A
Rationale: Research has shown that smoking during adolescence is closely linked to engaging in other high-risk behaviors, such as alcohol and drug use, risky sexual behavior, and delinquency. Adolescents who smoke are more likely to experiment with other substances and engage in risky activities compared to non-smokers. This is due to common psychological and sociocultural factors that contribute to the clustering of risky behaviors among adolescents. Therefore, statement A is the most accurate description of the relationship between smoking and high-risk behaviors in adolescence.
Mr Santos is scheduled for CT SCAN for the next day, noon time. Which of the following is the correct preparation as instructed by the nurse?
- A. Shampoo hair thoroughly to remove oil and dirt
- B. No special preparation is needed. Instruct the patient to keep his head still and stead
- C. Give a cleansing enema and give fluids until 8 AM
- D. Shave scalp and securely attach electrodes to it
Correct Answer: A
Rationale: The correct preparation for a CT scan, in this case, does not involve any special instructions such as shampooing hair, giving an enema, or shaving the scalp. The patient is simply instructed to keep their head still and steady during the scan. CT scans do not require any specific preparation unless explicitly stated by the healthcare provider conducting the test. It is important to follow the nurse's or healthcare provider's instructions carefully to ensure the best results from the CT scan.
The nurse evaluates that furosemide IV is effective in treating pulmonary edema if which of the following patient signs or symptoms is resolved?
- A. Pedal edema
- B. Pink, frothy sputum
- C. Jugular vein distention
- D. Bradycardia
Correct Answer: B
Rationale: Furosemide IV is a diuretic medication commonly used to treat conditions such as pulmonary edema. In the case of pulmonary edema, the excess fluid accumulates in the lungs, leading to symptoms such as difficulty breathing, wheezing, and the production of pink, frothy sputum. The presence of pink, frothy sputum is a classic sign of pulmonary edema and indicates the presence of fluid in the airways. Therefore, the nurse would evaluate the effectiveness of furosemide IV treatment by monitoring the resolution of this specific symptom, as it indicates improvement in the underlying condition of pulmonary edema.
Which characteristic is representative of the newborn's gastrointestinal tract?
- A. Stomach capacity is approximately 90 ml.
- B. Peristaltic waves are relatively slow.
- C. Overproduction of pancreatic amylase occurs.
- D. Intestines are shorter in relation to body size.
Correct Answer: D
Rationale: The characteristic representative of the newborn's gastrointestinal tract is that the intestines are shorter in relation to the body size. This is because a newborn's gastrointestinal tract is still developing and adapting to the digestion and absorption of nutrients. The proportion of the intestines to the body size is smaller in newborns compared to adults. Over time, as the newborn grows and matures, the intestines will also lengthen and increase in capacity to efficiently process food and absorb nutrients.
For a client with sickle cell anemia, how does the nurse assess for jaundice?
- A. The nurse assesses mental status, verbal ability, and motor strength
- B. The nurse observes the joints for signs of swelling
- C. The nurse inspects the skin and sclera for jaundice
- D. The nurse collects a urine specimen
Correct Answer: C
Rationale: In a client with sickle cell anemia, jaundice is a common manifestation due to the breakdown of red blood cells. The nurse should inspect the skin and sclera for signs of jaundice, which presents as a yellow discoloration. This assessment helps in identifying the presence and severity of jaundice in the client, which can be indicative of ongoing hemolysis and the need for further interventions. Monitoring for jaundice is important in managing clients with sickle cell anemia to address complications early and provide appropriate care.
