Nursing Elites

1. The nurse is performing tuberculosis (TB) skin tests in a clinic that has many patients who have immigrated to the United States. Which question is most important for the nurse to ask before the skin test?

• A. Is there any family history of TB?
• B. How long have you lived in the United States?
• C. Do you take any over-the-counter (OTC) medications?
• D. Have you received the bacille Calmette-Guerin (BCG) vaccine for TB?

Correct answer: D

Rationale: It is crucial for the nurse to inquire about whether the patient has received the bacille Calmette-Guerin (BCG) vaccine for TB before performing the skin test. Patients who have received the BCG vaccine can have a positive Mantoux test, leading to the need for alternative screening methods, such as a chest x-ray, to determine TB infection. While family history of TB and length of time in the United States are relevant factors, they do not directly impact the decision to perform the TB skin test. Asking about over-the-counter medications, unless relevant to TB treatment, is not as critical as assessing BCG vaccination status.

2. A client has developed a vitamin C deficiency. Which of the following symptoms might the nurse most likely see with this condition?

• A. Cracks at the corners of the mouth
• B. Altered mental status
• C. Bleeding gums and loose teeth
• D. Anorexia and diarrhea

Correct answer: C

Rationale: A client with a severe vitamin C deficiency has a condition called scurvy. Scurvy is characterized by symptoms such as bleeding gums, loose teeth, poor wound healing, and easy bruising. The correct answer is 'Bleeding gums and loose teeth' because these are classic signs of scurvy due to vitamin C deficiency. Choice A ('Cracks at the corners of the mouth') is more indicative of a deficiency in B vitamins, specifically riboflavin. Choice B ('Altered mental status') is not typically associated with vitamin C deficiency but can occur with other conditions like vitamin B12 deficiency. Choice D ('Anorexia and diarrhea') are not common symptoms of vitamin C deficiency, as they are more commonly associated with other gastrointestinal issues or deficiencies in different nutrients.

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. The nurse is caring for an infant with cryptorchidism. The nurse anticipates that the most likely diagnostic study to be prescribed would be the one that assesses which item?

• A. Babinski reflex
• B. DNA synthesis
• C. Urinary function
• D. Chromosomal analysis

Correct answer: C

Rationale: Cryptorchidism, also known as undescended testes, may be caused by hormonal deficiency, intrinsic testicular abnormality, or a structural problem. Diagnostic studies for cryptorchidism typically involve assessing urinary function because the kidneys and testes originate from the same embryonic tissue. The Babinski reflex is a test for neurological function and is not relevant to evaluating cryptorchidism. DNA synthesis and chromosomal analysis are not commonly used diagnostic tests for cryptorchidism, as they are unrelated to the disorder's etiology or presentation.

5. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

• A. Administer bicarbonate.
• B. Complete a head-to-toe assessment.
• C. Place the patient on high-flow oxygen.
• D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.
