Nursing Elites

1. Your patient has shown the following signs and symptoms: Feeling very thirsty, large amount of water intake, dryness of the mouth, and urinary frequency. What physical disorder does this patient most likely have?

• A. Diabetes
• B. Angina
• C. Hypertension
• D. Hypotension

Correct answer: A

Rationale: The patient is exhibiting classic signs of diabetes, such as polydipsia (feeling very thirsty), polyuria (large amount of water intake and urinary frequency), and xerostomia (dryness of the mouth). These symptoms are indicative of high blood glucose levels, which are characteristic of diabetes. Other common signs of diabetes include poor vision, unexplained weight loss, peripheral neuropathy (tingling in the feet and hands), and fatigue. Angina is chest pain due to reduced blood flow to the heart, not associated with the symptoms described in the patient. Hypertension is high blood pressure, which typically does not present with these specific symptoms related to diabetes. Hypotension is low blood pressure and is not consistent with the signs and symptoms presented by the patient, pointing more towards diabetes as the likely diagnosis.

2. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

3. 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.

4. A child is suspected of suffering from intussusception. The nurse should be alert to which clinical manifestation of this condition?

• A. Tender, distended abdomen
• B. Presence of fecal incontinence
• C. Incomplete development of the anus
• D. Infrequent and difficult passage of dry stools

Correct answer: A

Rationale: Intussusception is an invagination of a section of the intestine into the distal bowel, and it is the most common cause of bowel obstruction in children aged 3 months to 6 years. A tender, distended abdomen is a typical clinical manifestation of intussusception. The presence of fecal incontinence is not a characteristic presentation of intussusception; it describes encopresis, which generally affects preschool and school-aged children but is not specific to intussusception. Incomplete development of the anus describes imperforate anus, a disorder diagnosed in the neonatal period, not intussusception. The infrequent and difficult passage of dry stools is characteristic of constipation, a common issue in children that can occur at any age, although it often peaks at 2 to 3 years old.

5. 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.
