When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?
- A. 2 liters/minute
- B. 4 liters/minute
- C. 6 liters/minute
- D. 8 liters/minute
Correct Answer: C
Rationale: The correct answer is 6 liters/minute. When a client needs oxygen therapy, the highest flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Higher flow rates must be delivered by a mask. Choices A, B, and D are incorrect because they suggest flow rates that exceed what can be effectively delivered through a nasal cannula.

In an obstetrical emergency, which of the following actions should the nurse perform first after the baby delivers?
- A. Place extra padding under the mother to absorb blood from the delivery.
- B. Cut the umbilical cord using sterile scissors.
- C. Suction the baby's mouth and nose.
- D. Wrap the baby in a clean blanket to preserve warmth.
Correct Answer: C
Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.
How often should physical restraints be released?
- A. Every 2 hours
- B. Between 1 and 3 hours
- C. Every 30 minutes
- D. At least every 4 hours
Correct Answer: A
Rationale: The correct answer is to release physical restraints every 2 hours. Releasing restraints every 2 hours helps prevent complications associated with prolonged immobilization. Releasing restraints every 30 minutes (choice C) may be too frequent and disruptive to the client's care. Releasing restraints between 1 and 3 hours (choice B) introduces variability that could lead to inconsistencies in care. Releasing restraints at least every 4 hours (choice D) does not adhere to the recommended frequency of every 2 hours.
Which of the following statements describes the purpose of client restraint?
- A. Restraints are a nursing measure used to maintain client control.
- B. Restraints are an emergency intervention taken as a last resort to protect a client from imminent danger.
- C. Restraints are a therapeutic measure designed to positively reinforce client behavior.
- D. Restraints are an emergency measure that can only be taken by a nurse under the direct supervision of a physician.
Correct Answer: B
Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.
A young boy is recently diagnosed with a seizure disorder. Which of the following statements by the boy's mother indicates a need for further teaching by the nurse?
- A. "I should make sure he gets plenty of rest."?
- B. "I should get him a medical alert bracelet."?
- C. "I should lay him on his back during a seizure."?
- D. "I should loosen his clothing during a seizure."?
Correct Answer: C
Rationale: The correct answer is "I should lay him on his back during a seizure."? This statement indicates a need for further teaching because a client having a seizure should be turned to the side to prevent aspiration of secretions. Choices A, B, and D are correct. Getting plenty of rest helps in managing seizures, having a medical alert bracelet informs others about the condition in case of emergency, and loosening clothing during a seizure ensures better air circulation and prevents injury. These actions demonstrate adequate understanding of the teaching provided.
For which condition might a client's antidiuretic hormone (ADH) level be increased?
- A. diabetes mellitus
- B. diabetes insipidus
- C. hypothyroidism
- D. hyperthyroidism
Correct Answer: B
Rationale: The correct answer is diabetes insipidus. In this condition, the client's ADH level is increased. Diabetes insipidus is characterized by the inability of the kidneys to conserve water due to either inadequate secretion of ADH (central diabetes insipidus) or the kidneys' inability to respond to ADH (nephrogenic diabetes insipidus). Choices A, C, and D are incorrect. In diabetes mellitus, ADH levels are typically normal or elevated in response to high blood sugar levels. Hypothyroidism is not directly related to ADH secretion. In hyperthyroidism, ADH levels are usually normal or decreased.
