What size of suction catheter would Wilma use for James, who is 6 feet 5 inches in height and weighing approximately 145 lbs?
- A. Fr. 5
- B. Fr. 12
- C. Fr. 10
- D. Fr. 18
Correct Answer: C
Rationale: The correct size of a suction catheter is usually determined by the patient's weight, rather than height. For James, who weighs approximately 145 lbs, a Fr. 10 suction catheter would be suitable. Suction catheter sizes typically range from Fr. 5 (smaller) to Fr. 18 (larger), with Fr. 10 being a common size for an adult patient of James' weight. Using a catheter that is too small may not effectively clear secretions, while one that is too big may cause discomfort or damage to the airways.

What is the best initial action for the nurse to take?
- A. Try to have the client breathe slower or
- B. Give O2 via nasal cannula into the paper bag
- C. Administer sodium bicarbonate
- D. Monitor the client's fluid balance
Correct Answer: A
Rationale: The best initial action for the nurse to take when a client is experiencing hyperventilation is to try to have the client breathe slower. This is because hyperventilation is often caused by rapid, shallow breathing and slowing down the breathing pattern can help restore normal gas exchange and alleviate symptoms. Providing oxygen via a nasal cannula or administering sodium bicarbonate would not directly address the underlying issue of hyperventilation. Monitoring fluid balance is important for overall assessment but not the priority when dealing with acute respiratory distress due to hyperventilation.
Choose the condition that exhibits blood values with a low pH and a high PCO :
- A. Respiratory acidosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Metaboliâ‚‚c alkalosis
Correct Answer: A
Rationale: Respiratory acidosis is a condition characterized by elevated levels of carbon dioxide (high PCOâ‚‚) and decreased blood pH (low pH) due to inadequate ventilation leading to the accumulation of carbon dioxide in the body. The excess carbon dioxide reacts with water in the blood to form carbonic acid, resulting in a decrease in pH. This is in contrast to metabolic acidosis, which is characterized by an accumulation of acids other than carbon dioxide, leading to a low blood pH. Respiratory alkalosis would present with a low PCOâ‚‚ and high pH, while metabolic alkalosis features a high pH and elevated bicarbonate levels due to non-respiratory causes.
The adrenal cortex is responsible for producing which substances?
- A. Glucocortocoids and androgens
- B. Mineralocortiroids and
- C. Catecholamines and epinephrine catecholamines
- D. Norepinephine and epinephrine
Correct Answer: A
Rationale: The adrenal cortex is the outer portion of the adrenal glands and is responsible for producing hormones known as corticosteroids. Within the corticosteroids, the adrenal cortex produces glucocorticoids (such as cortisol) which are involved in regulating metabolism and the immune response. Additionally, the adrenal cortex produces androgens which are male sex hormones, although they are present in both males and females. Therefore, the correct substances produced by the adrenal cortex are glucocorticoids and androgens (Choice A).
The physical manifestations of fetal alcohol syndrome include:
- A. abnormal facial tissue, cleft lip, and cleft palate.
- B. hepatomegaly, hypotonia, and microphthalmia.
- C. microcephaly, short philtrum, and intrauterine growth restriction.
- D. hyperbilirubinemia, jaundice, and failure to thrive.
Correct Answer: C
Rationale: Fetal alcohol syndrome is characterized by microcephaly, a short philtrum, and intrauterine growth restriction, among other features.
