Nursing Elites

1. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?

• A. Diarrhea
• B. Metabolic acidosis
• C. Metabolic alkalosis
• D. Hyperactive bowel sounds

Correct answer: C

Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.

2. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

3. A patient with bacterial pneumonia has rhonchi and thick sputum. What is the nurse's most appropriate action to promote airway clearance?

• A. Assist the patient to splint the chest when coughing.
• B. Teach the patient about the need for fluid intake.
• C. Encourage the patient to wear the nasal oxygen cannula.
• D. Instruct the patient on the pursed lip breathing technique.

Correct answer: A

Rationale: Assisting the patient to splint the chest when coughing is the most appropriate action to promote airway clearance in a patient with bacterial pneumonia, rhonchi, and thick sputum. Splinting the chest helps reduce pain during coughing and increases the effectiveness of clearing secretions. Teaching the patient about the need for fluid intake is important as it helps liquefy secretions, aiding in easier clearance. Encouraging the patient to wear a nasal oxygen cannula may improve gas exchange but does not directly promote airway clearance. Instructing the patient on the pursed lip breathing technique is beneficial for improving gas exchange in patients with COPD but does not directly aid in airway clearance in a patient with bacterial pneumonia and thick sputum.

4. What preparation should be made for a client undergoing a KUB (Kidney, Ureter, Bladder) radiography test?

• A. Client must be NPO before the examination
• B. Enema should be administered before the examination
• C. Medicate the client with furosemide 20 mg IV 30 minutes before the examination
• D. No special orders are necessary for this examination

Correct answer: D

Rationale: The correct answer is that no special orders are necessary for a KUB radiography test. It is important to inform the client to remove any clothing, jewelry, or objects that may interfere with the test. Option A is incorrect because there is no need for the client to be NPO before this examination. Option B is incorrect as enemas are not routinely administered prior to a KUB radiography test. Option C is incorrect as there is no need to medicate the client with furosemide before this examination.

5. A client is undergoing radiation therapy for treatment of thyroid cancer. Following the radiation, the client develops xerostomia. Which of the following best describes this condition?

• A. Cracks in the corners of the mouth
• B. Peeling skin from the tongue and gums
• C. Increased dental caries
• D. Dry mouth

Correct answer: D

Rationale: Xerostomia, also known as dry mouth, is a common side effect of radiation therapy in the head and neck region. It occurs when the salivary glands are damaged during treatment, reducing saliva production and causing a dry sensation in the mouth. The correct answer is 'Dry mouth' (option D). Choice A, 'Cracks in the corners of the mouth,' describes angular cheilitis, a condition linked to nutritional deficiencies or candida infection. Choice B, 'Peeling skin from the tongue and gums,' is more indicative of conditions like oral thrush or mucositis. Choice C, 'Increased dental caries,' is a consequence of reduced saliva flow but does not specifically describe xerostomia.
