The nurse is working on an infectious disease unit. Which client should be assigned to a room with negative airflow, while requiring personnel to use a particulate respirator mask, and requiring staff to observe airborne, as well as standard precautions?

A female adolescent admitted with multiple genital Herpes simplex II lesions.

Twin siblings admitted with scarlet fever that is complicated with pneumonia.

An older client with scabies who is admitted from an extended care facility.

A client with a positive Mantoux and sputum cultures results positive for acid-fast bacillus (AFB).

Answer and Explanation

The Correct Answer is D

Rationale

A. Herpes simplex virus type II (HSV-II) primarily spreads through direct contact with the lesions and is not airborne. Airborne precautions and negative airflow rooms are not necessary for this condition.

B. Scarlet fever is caused by Group A Streptococcus bacteria and typically spreads through respiratory droplets. However, scarlet fever itself does not require airborne precautions. If complicated with pneumonia, respiratory droplets could potentially spread the infection, but specific airborne precautions are generally not required unless there are other pathogens involved that require it.

C. Scabies is caused by the Sarcoptes scabiei mite and spreads through direct skin-to-skin contact. It does not require airborne precautions or negative airflow rooms.

D. A positive Mantoux test and sputum cultures positive for acid-fast bacillus (AFB) suggest tuberculosis (TB) infection. TB is spread through airborne droplets (e.g., coughing, sneezing), and therefore, requires airborne precautions including negative airflow rooms to prevent transmission to others.A

Correct Answer is B

Explanation

Rationale

A. Aspirin is commonly used in the emergency setting for chest pain suspected to be due to acute coronary syndrome (ACS), which includes conditions like myocardial infarction (heart attack). It works by reducing blood clotting and can help alleviate symptoms in some cases. It is typically safe to administer aspirin

B. Sildenafil can interact with nitrates, such as nitroglycerin, and result in a significant drop in blood pressure. Therefore, the nurse should withhold nitroglycerin to prevent potential adverse effects.

C. Morphine is a potent opioid pain medication used in the emergency department for severe pain relief, including chest pain associated with suspected myocardial infarction. It can help reduce pain and anxiety in acute coronary syndromes. It has no significant interaction with sildenafil.

D. Heparin is an anticoagulant medication used to prevent blood clotting. It is often administered in the hospital setting for various indications, such as deep vein thrombosis, pulmonary embolism, or in some cases of acute coronary syndromes.

A. Increase rate of ventilation. B. Decrease expiratory flow time. C. Increase ventilator tidal volume. D. Decrease expiratory pressure.

Correct Answer is A

Explanation

Rationale

A. The client's pH is low (acidotic), and the PaCO2 is high (respiratory acidosis). Increasing the rate of ventilation (respiratory rate) can help to decrease PaCO2 by increasing alveolar ventilation, thereby helping to correct respiratory acidosis.

B. Expiratory flow time affects the time available for exhalation. While this may affect the overall mechanics of ventilation, it is not directly targeting the primary issue of elevated PaCO2 and acidosis.

C. Increasing tidal volume increases the volume of air delivered with each breath. This can improve ventilation efficiency but may not address the underlying problem of elevated PaCO2 unless it leads to increased minute ventilation.

D. Expiratory pressure is related to positive end-expiratory pressure (PEEP), which helps maintain alveolar recruitment and improve oxygenation. Decreasing expiratory pressure may not directly address the elevated PaCO2 and acidosis.
