A 17-year-old student enters the emergency department with a nosebleed that won't quit. Which of the following positions is recommended for the patient with a nosebleed?

Correct Answer: D

Rationale: The recommended position for a patient with a nosebleed is sitting up and leaning slightly forward. This position helps prevent blood from flowing down the back of the throat, which can cause gagging, choking, or vomiting. Leaning forward also helps to prevent blood from accumulating in the sinuses, reducing the risk of aspiration. Additionally, this position allows easy access to apply pressure to the nostrils to help stop the bleeding. It is essential to avoid lying down or tilting the head back, as this can lead to swallowing blood and potentially cause further complications.

Correct Answer: D

Rationale: Scratching the lesions caused by poison ivy may result in them becoming secondarily infected. It is important to advise against scratching the affected areas to prevent the introduction of bacteria from under the fingernails or through broken skin, which can lead to infection. This can complicate the initial skin irritation caused by the poison ivy rash. Encouraging the child to avoid scratching and keeping the affected areas clean can help prevent secondary infections and promote healing.

Correct Answer: D

Rationale: Postauricular, occipital, and cervical lymphadenopathy are characteristic signs of rubella, often preceding the rash.

Correct Answer: D

Rationale: Tachycardia is an early compensatory response to shock to maintain cardiac output.

Correct Answer: C

Rationale: Digitalis is not used in resuscitation as it primarily treats heart failure and certain arrhythmias rather than acute cardiac arrest situations requiring immediate resuscitative drugs.
