Correct Answer: A

Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.

Correct Answer: A

Rationale: The correct action for the nurse to take when caring for a client with Clostridium difficile in contact isolation is to wear gloves when changing the client's gown. Clostridium difficile is highly transmissible, and wearing gloves helps prevent the spread of the infection. Using hand sanitizer after contact with the client (Choice B) is not enough to prevent the transmission of C. difficile, as the spores can persist and spread. Wearing a mask when entering the client's room (Choice C) is not necessary for C. difficile transmission, which primarily occurs through contact with contaminated surfaces. Cleaning the room with a disinfectant spray (Choice D) is important, but wearing gloves during direct care is the priority to prevent the nurse from acquiring and spreading the infection.

Correct Answer: B

Rationale: The nurse is about to commit false imprisonment by unlawfully restricting the client's freedom of movement. In this scenario, the nurse's actions of preparing to administer sedative medication against the client's will in an effort to prevent them from leaving the hospital constitute false imprisonment. Assault (choice A) involves the threat of bodily harm, which is not present here. Negligence (choice C) refers to a breach in the duty of care, which is not the primary issue in this situation. Breach of confidentiality (choice D) involves disclosing confidential information without consent, which is unrelated to the scenario described.

Correct Answer: B

Rationale: Corrected Rationale: Assessing skin color is crucial to evaluate perfusion and circulation postoperatively. Skin color changes can indicate compromised circulation, such as pallor or cyanosis. Edema may suggest fluid retention but is not a direct indicator of circulation status. Range of motion is more related to joint function and mobility, not specifically circulation.

Correct Answer: C

Rationale: An increasing pulse rate can be an early sign of poor oxygenation as the body tries to compensate. Abnormal breath sounds (choice A) can indicate respiratory issues, but they may not always be an early sign of poor oxygenation. Cyanosis of the lips (choice B) is a late sign of inadequate oxygenation. A pulse oximeter reading of 92% (choice D) indicates mild hypoxemia but may not be considered an early indication of poor oxygenation.
