Nursing Elites

1. The nurse caring for Mrs. J is prepared to suction her endotracheal tube. Which of the following interventions will reduce hypoxia during this procedure?

• A. Hyperoxygenate Mrs. J for up to 60 seconds prior to starting
• B. Administer 15 mL of sterile fluid into the tube prior to suctioning
• C. Suction for no longer than 30 seconds at a time
• D. Wait 30 seconds after suctioning before attempting again

Correct answer: A

Rationale: Before suctioning a client's endotracheal tube, it is essential to hyperoxygenate the client for approximately 30 to 60 seconds. Hyperoxygenation helps increase oxygen delivery to the tissues, reducing the risk of hypoxia during and after the suctioning procedure. Administering fluid into the tube before suctioning (Choice B) is unnecessary and can lead to complications. Suctioning for no longer than 30 seconds at a time (Choice C) is a general guideline but does not specifically address reducing hypoxia. Waiting 30 seconds after suctioning before attempting again (Choice D) may lead to inadequate oxygenation and potential hypoxia, making it less effective in preventing this complication compared to hyperoxygenation prior to suctioning.

2. The nurse palpates the posterior chest while the patient says 99 and notes absent fremitus. What action should the nurse take next?

• A. Auscultate anterior and posterior breath sounds bilaterally
• B. Encourage the patient to turn, cough, and deep breathe
• C. Review the chest x-ray report for evidence of pneumonia
• D. Palpate the anterior chest and observe for barrel chest

Correct answer: A

Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.

3. During your evaluation of a 14-year-old girl with a BMI of 18, she reports inability to eat, induced vomiting, and severe constipation. Which of the following would you most likely suspect?

• A. Multiple sclerosis
• B. Anorexia nervosa
• C. Bulimia nervosa
• D. Systemic sclerosis

Correct answer: B

Rationale: The clinical presentation described in the question is highly suggestive of anorexia nervosa. Anorexia nervosa is characterized by self-imposed starvation due to a distorted body image and an intense fear of gaining weight, even when the individual is underweight. The patient's symptoms of inability to eat, induced vomiting, and severe constipation align with the behavior seen in anorexia nervosa, including restrictive eating patterns and purging behaviors. Multiple sclerosis (Choice A) is a neurological disorder, not associated with the described symptoms. Bulimia nervosa (Choice C) typically involves binge eating followed by purging behaviors, which is different from the described primary restriction seen in anorexia nervosa. Systemic sclerosis (Choice D) is a connective tissue disorder and is not related to the symptoms of self-induced vomiting and severe constipation reported in this case.

4. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?

• A. The life span of RBC is 45 days
• B. The life span of RBC is 60 days
• C. The life span of RBC is 90 days
• D. The life span of RBC is 120 days

Correct answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.

5. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
