Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
A nurse administers 12 units lispro insulin at 0700 to a client. Within which time frame must the morning meal be served?
Correct Answer: A
Rationale: The client should consume their meal immediately, but no longer than 15 minutes after receiving this rapid acting insulin. The onset of humalog insulin is 15-30 minutes, peak time is 30 min to 2.5 hours, with a duration of 3-6 hours.
Question 2 of 5
The nurse is caring for a patient on a ventilator and reads the order "restrain prn." The nurse considers which factor when caring for this patient? (Select all that apply)
Correct Answer: C
Rationale: Safety restraint devices (SRDs) are used to protect patients but must be applied correctly to avoid harm. SRDs do not inherently decrease anxiety (A) and may increase it if misused. Not all older adults need SRDs at night (B) as this is not a blanket requirement and should be individualized. Allowing maximum freedom of movement (C) is correct to prevent injury and maintain comfort. Tying SRDs to side rails (D) is unsafe as it can cause injury if the rail moves; they should be tied to the bed frame. Ensuring two fingers can fit between the SRD.
Question 3 of 5
A home health nurse is discussing the dangers of food poisoning with a client. Which of the following information should the nurse include? (Select one that doesn't apply.)
Correct Answer: A
Rationale: Food poisoning is often caused by bacteria (e.g. Salmonella E. coli) not primarily viruses (A is incorrect but listed). Immunocompromised individuals (B) are at higher risk for severe complications. High-risk clients should use pasteurized dairy (C) to avoid pathogens. Despite the error in A the document lists A B and C as correct emphasizing the need for accurate education on food safety.
Question 4 of 5
The client is experiencing severe shortness of breath,but is not cyanotic. What laboratory value should the nurse review in an attempt to understand this phenomenon?
Correct Answer: B
Rationale: Cyanosis requires at least 5 g/dL of unoxygenated hemoglobin and dilated surface capillaries. Severe anemia (low hemoglobin/hematocrit B) can prevent cyanosis despite hypoxia as insufficient hemoglobin limits visible deoxygenation. Blood sugar (A) cardiac enzymes (C) and electrolytes (D) do not explain the absence of cyanosis making B the relevant lab value to review.
Question 5 of 5
The nurse has placed an oropharyngeal airway in a client. What action should the nurse take at this time?
Correct Answer: C
Rationale: An oropharyngeal airway facilitates airflow but can stimulate secretions. Turning the head to the side (C) allows drainage of oral secretions preventing aspiration. Taping (A) is not standard as the airway is temporary. Suctioning (B) may be needed but is not the immediate action. A nasal trumpet (D) is a different device making C the appropriate action to ensure airway patency and safety.
