1. Which mineral-containing amino acids help to form the shape of proteins?
- A. phosphorus
- B. sulfur
- C. selenium
- D. iron
Correct answer: B
Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.
2. A nurse is caring for an infant who has a prescription for continuous pulse oximetry. Which of the following is an appropriate action for the nurse to take?
- A. Place the infant under a radiant warmer
- B. Move the probe site every 3 hours
- C. Heat the skin one minute prior to placing the probe
- D. Place a sensor on the index finger
Correct answer: B
Rationale: The correct answer is to move the probe site every 3 hours. This action helps prevent skin breakdown and ensures accurate readings. Placing the infant under a radiant warmer (Choice A) is not necessary for pulse oximetry monitoring. Heating the skin before placing the probe (Choice C) can potentially cause burns in infants. Placing a sensor on the index finger (Choice D) is not the standard practice for continuous pulse oximetry in infants.
3. Which of the following is not a side effect of loop diuretics?
- A. Alkalosis
- B. Nausea
- C. Hypotension
- D. Potassium deficits
Correct answer: B
Rationale: Nausea is not commonly associated with loop diuretics. Loop diuretics are known to cause electrolyte imbalances such as potassium deficits, metabolic alkalosis, and hypotension due to excessive fluid loss. Nausea is not a typical side effect of loop diuretics.
4. Testosterone production is regulated by which of the following glands?
- A. Pineal
- B. Thymus
- C. Parathyroid
- D. Pituitary
Correct answer: D
Rationale: Testosterone production is regulated by the pituitary gland. The pituitary gland secretes luteinizing hormone (LH), which stimulates the Leydig cells in the testes to produce testosterone. This hormone is not regulated by the Pineal, Thymus, or Parathyroid glands. The Pineal gland is responsible for secreting melatonin, the Thymus gland is involved in immune function, and the Parathyroid glands regulate calcium levels in the blood.
5. A client with asthma is taking fluticasone. The nurse should monitor the client for which of the following adverse effects?
- A. Hypoglycemia
- B. Hypertension
- C. Polyuria
- D. Oral candidiasis
Correct answer: D: Oral candidiasis
Rationale: Fluticasone is a corticosteroid often used to manage asthma. One of the common adverse effects associated with inhaled corticosteroids like fluticasone is oral candidiasis, also known as thrush. This fungal infection can develop in the mouth and throat due to the steroid's local immunosuppressive effects. Patients should be advised to rinse their mouths after using inhaled corticosteroids to reduce the risk of oral candidiasis. Monitoring for symptoms such as white patches, sore throat, or difficulty swallowing is essential to detect and manage this adverse effect promptly.
