What is the appropriate route of administration for insulin?

A. Intramuscular

B. Intradermal

C. Subcutaneous

D. Intravenous

Correct Answer: C
Rationale: The appropriate route of administration for insulin is subcutaneous. Subcutaneous injections are commonly used for insulin administration due to the slower absorption rate compared to intramuscular or intravenous routes. This slower absorption rate allows for better control of blood glucose levels. Intramuscular administration is not ideal for insulin as it can lead to rapid absorption and fluctuations in blood sugar levels. Intradermal injections are shallow and used for skin testing rather than insulin administration. Intravenous administration of insulin is not recommended due to the rapid and unpredictable effects it can have on blood glucose levels.

A healthcare professional is assessing a client following a gunshot wound to the chest. For which of the following findings should the healthcare professional not monitor to detect a pneumothorax?

• A. Tachypnea
• B. Deviation of the trachea
• C. Bradycardia
• D. Pleuritic pain

Correct Answer: C: Bradycardia
Rationale: Bradycardia, which is a slow heart rate, is not typically associated with a pneumothorax. In a pneumothorax, the presence of air in the pleural space can lead to lung collapse, causing symptoms such as tachypnea (rapid breathing), deviation of the trachea, and pleuritic pain. Monitoring for bradycardia may not be as relevant in this context as it is not a typical indicator of a pneumothorax.

Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?

• A. Opening the patient’s window to the outside environment
• B. Turning on the patient’s room ventilator
• C. Opening the door of the patient’s room leading into the hospital corridor
• D. Failing to wear gloves when administering a bed bath

Correct Answer: D
Rationale: Failure to wear gloves during a bed bath can potentially introduce pathogens, compromising the sterile technique necessary for respiratory isolation. Proper hand hygiene and personal protective equipment are crucial to prevent the transmission of infectious agents in such settings.

Which of the following is the correct meaning of CBR?

• A. Cardiac Board Room
• B. Complete Bathroom
• C. Complete Bed Rest
• D. Complete Board Room

Correct Answer: C
Rationale: In medical terminology, 'CBR' stands for Complete Bed Rest. This term indicates the necessity for a patient to remain in bed without engaging in any physical activities beyond what is essential for daily living, to aid in the recovery process or to prevent further health complications. Choices A, B, and D are incorrect as they do not reflect the medical meaning of CBR.

The healthcare professional must verify the client’s identity before the administration of medication. Which of the following is the safest way to identify the client?

• A. Ask the client for their name
• B. Check the client’s identification band
• C. State the client’s name aloud and ask the client to repeat it
• D. Check the room number

Correct Answer: B
Rationale: Verifying the client's identity before administering medication is crucial to ensure patient safety. Checking the client’s identification band is the safest and most reliable method to confirm the client's identity. Identification bands are specifically designed to prevent errors in patient identification and help healthcare professionals administer care to the correct individual. Asking the client for their name (Choice A) may lead to errors if the client is unable to communicate or if there is a language barrier. Stating the client’s name aloud and asking them to repeat it (Choice C) relies on the client's ability to respond accurately. Checking the room number (Choice D) does not directly confirm the client's identity and may lead to errors if multiple patients are in the same room.
