Question 1 of 5
A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?
Correct Answer: A
Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.
Question 2 of 5
Priorities designated as intermediate by the nurse are:
Correct Answer: A
Rationale: Priorities designated as intermediate by the nurse are those that are not urgent but still important, such as the nonemergency, non-life-threatening needs of the client. They do not impact the client's immediate physiological status but require attention. Intermediate priorities may need the skill level of an RN for completion and may have specific time requirements.
Choices B, C, and D are incorrect because the priority being intermediate doesn't mean it can be delegated, done at a specific time, or done at any time; it simply indicates a non-urgent but necessary task for the client's well-being.
Question 3 of 5
What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1°F at 4 a.m.?
Correct Answer: D
Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1°F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m.
Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.
Question 4 of 5
In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?
Correct Answer: A
Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life.
Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.
Question 5 of 5
Acyclovir (Zovirax) is the agent of choice for which of the following infections?
Correct Answer: D
Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir.
Therefore, the correct answer is herpes.
