1. Administration of hepatitis B vaccine to a healthy 18-year-old patient has been effective when a specimen of the patient's blood reveals

• A. HBsAg.
• B. anti-HBs
• C. anti-HBc IgG
• D. anti-HBc IgM.

Correct answer: B

Rationale: The correct answer is 'anti-HBs'. The presence of surface antibody to HBV (anti-HBs) indicates a successful response to the hepatitis B vaccine. Anti-HBs is a marker of immunity and protection against hepatitis B infection. Choices A, C, and D are incorrect because: A) HBsAg indicates current infection with hepatitis B virus, C) anti-HBc IgG suggests past infection or immunity, and D) anti-HBc IgM is a marker of acute hepatitis B infection.

2. The patient's symptoms, lack of antibodies for hepatitis, and the abrupt onset of symptoms suggest toxic hepatitis, which can be caused by commonly used over-the-counter drugs such as acetaminophen (Tylenol). Travel to a foreign country and a history of IV drug use are risk factors for viral hepatitis. Corticosteroid use does not cause the symptoms listed.

• A. Hemoglobin
• B. Temperature
• C. Activity level
• D. Albumin level

Correct answer: D

Rationale: The low oncotic pressure caused by hypoalbuminemia is a major pathophysiologic factor in the development of edema. In this case, monitoring the albumin level is crucial to assess the patient's fluid balance and potential for edema. While hemoglobin, temperature, and activity level are important parameters to monitor in a patient's assessment, they are not directly associated with the patient's current symptoms of toxic hepatitis and edema development. Therefore, the correct choice is the albumin level.

3. Which of the following measures would be appropriate for a nurse to teach the parent of a nine-month-old infant about diaper dermatitis?

• A. Use only cloth diapers that are rinsed in bleach
• B. Do not use occlusive ointments on the rash
• C. Use commercial baby wipes with each diaper change
• D. Discontinue a new food that was added to the infant's diet just prior to the rash

Correct answer: D

Rationale: Diaper dermatitis can be caused by various factors, one of which includes introducing new foods to the infant's diet. Discontinuing the new food that was added just before the rash can help identify and eliminate the potential cause. Options A and C are not directly related to addressing the cause of diaper dermatitis. While using cloth diapers rinsed in bleach may be a preventive measure for diaper dermatitis, it is not addressing a specific cause. Option B, advising against using occlusive ointments on the rash, may actually be beneficial in managing diaper dermatitis, but it does not address the cause of the condition.

4. A patient with pneumonia has a fever of 101.4 F (38.6 C), a nonproductive cough, and an oxygen saturation of 88%. The patient complains of weakness, fatigue, and needs assistance to get out of bed. Which nursing diagnosis should the nurse assign as the highest priority?

• A. Hyperthermia related to infectious illness
• B. Impaired transfer ability related to weakness
• C. Ineffective airway clearance related to thick secretions
• D. Impaired gas exchange related to respiratory congestion

Correct answer: D

Rationale: The correct answer is 'Impaired gas exchange related to respiratory congestion.' While all the nursing diagnoses are relevant to the patient's condition, the priority should be given to impaired gas exchange due to the patient's low oxygen saturation level of 88%. This indicates a significant risk of hypoxia for all body tissues unless the gas exchange is improved. Addressing impaired gas exchange is crucial to ensure adequate oxygenation and prevent further complications. Hyperthermia, impaired transfer ability, and ineffective airway clearance are important concerns but addressing gas exchange takes precedence in this scenario.

5. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.
