A frail, older adult home health patient who had chickenpox as a child has been exposed to varicella (chickenpox) several days ago. What should the nurse do?

Arrange for the patient to receive gamma globulin.

Assess frequently for herpes zoster.

Be aware of the patient's immunity to chickenpox.

Encourage the patient to have a pneumonia vaccine.

Answer and Explanation

The Correct Answer is C

A. Arrange for the patient to receive gamma globulin.

Gamma globulin is a blood product that contains antibodies and is sometimes used for post-exposure prophylaxis in certain situations, such as for individuals who are immunocompromised or pregnant and have been exposed to varicella (chickenpox) or measles. However, for a frail, older adult who had chickenpox as a child and has been exposed to varicella again, arranging for gamma globulin may not be necessary if the patient is already immune to chickenpox.

B. Assess frequently for herpes zoster.

Herpes zoster (shingles) is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. While exposure to varicella can increase the risk of developing shingles in individuals who are susceptible, frequent assessment for herpes zoster is not necessary in this case if the patient is known to have had chickenpox in the past.

C. Be aware of the patient's immunity to chickenpox.

This option is the correct choice. Since the patient had chickenpox as a child, they likely have immunity to chickenpox. Being aware of this immunity helps the nurse understand that the patient may not develop chickenpox again even after exposure to varicella.

D. Encourage the patient to have a pneumonia vaccine.

Encouraging the patient to have a pneumonia vaccine is unrelated to the immediate concern of exposure to varicella. While pneumonia vaccines are important for older adults, especially those who are frail, the priority in this scenario is to determine the patient's immunity to chickenpox due to prior infection.

Correct Answer is D

Explanation

A. Cardiac arrest related to septic shock:

Septic shock can occur in burn patients due to the breakdown of the skin barrier, which allows pathogens to enter the bloodstream and cause systemic infection. However, while septic shock is a serious complication of burn injuries, it is not the primary cause of death in the emergent phase. Septic shock can lead to multiple organ failure and contribute to mortality, but it is often a later complication rather than an immediate cause in the emergent phase.

B. Infection:

Infections are a significant concern in burn patients, especially as the burn wound provides an ideal environment for bacterial growth. However, infections typically contribute more significantly to mortality in the later phases of burn care rather than in the emergent phase. In the emergent phase, hypovolemic shock and other immediate complications have a greater impact on mortality.

C. Adrenal failure:

Adrenal failure, specifically acute adrenal insufficiency or Addisonian crisis, can occur in burn patients due to the stress response and corticosteroid depletion. While adrenal insufficiency is a concern in severe burn cases, it is not the primary cause of death in the emergent phase requiring referral to a burn center.

D. Hypovolemic shock and renal failure:

Hypovolemic shock is a critical concern in the emergent phase of burn trauma because burns can lead to significant fluid loss and electrolyte imbalances. Hypovolemic shock results from insufficient circulating blood volume, leading to inadequate perfusion of organs and tissues, which can be life-threatening. Additionally, renal failure can develop due to hypovolemia, decreased cardiac output, and the release of inflammatory mediators, leading to acute kidney injury (AKI). Hypovolemic shock and subsequent renal failure are major contributors to mortality in the emergent phase of burn trauma, necessitating prompt referral to a burn center for specialized care.

A. Diabetic ketoacidosis in a person with emphysema B. Diarrhea for 36 hours in an older, frail woman C. Anxiety-induced hyperventiIation in an adolescent D. Bronchial obstruction related to aspiration of a hot dog

Correct Answer is D

Explanation

A. Diabetic ketoacidosis (DKA) in a person with emphysema:

In DKA, there is typically metabolic acidosis due to the accumulation of ketones in the blood, leading to a decrease in pH. However, the respiratory compensation mechanism in DKA usually results in a decreased PaCO2 (respiratory alkalosis) rather than an elevated PaCO2 as seen in the blood gas values provided. Additionally, emphysema is associated with chronic respiratory acidosis, not respiratory alkalosis as indicated by the elevated PaCO2.

B. Diarrhea for 36 hours in an older, frail woman:

Prolonged diarrhea can lead to metabolic acidosis due to the loss of bicarbonate through the gastrointestinal tract. The pH of 7.12 and the decreased HCO3- (22 mEq/L) suggest metabolic acidosis. However, the elevated PaCO2 (respiratory acidosis) is not consistent with pure metabolic acidosis caused by diarrhea. Respiratory acidosis typically occurs due to hypoventilation or respiratory dysfunction.

C. Anxiety-induced hyperventilation in an adolescent:

Anxiety-induced hyperventilation can lead to respiratory alkalosis due to excessive blowing off of CO2, resulting in a decrease in PaCO2. The pH of 7.12 is consistent with acidosis, but the elevated PaCO2 contradicts respiratory alkalosis. Anxiety-induced hyperventilation would typically result in a higher pH and lower PaCO2.

D. Bronchial obstruction related to aspiration of a hot dog:

A bronchial obstruction causing inadequate ventilation can lead to respiratory acidosis due to CO2 retention. The pH of 7.12 and the elevated PaCO2 (65 mm Hg) indicate respiratory acidosis. This situation is consistent with the blood gas values provided.
