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. A patient is scheduled for a computed tomography (CT) of the chest with contrast media. Which assessment finding should the nurse immediately report to the health care provider?

• A. Patient is claustrophobic.
• B. Patient is allergic to shellfish.
• C. Patient recently used a bronchodilator inhaler.
• D. Patient is not able to remove a wedding band.

Correct answer: B

Rationale: The correct answer is that the patient is allergic to shellfish. This is crucial because the contrast media used in CT scans is iodine-based, and individuals with iodine allergies, such as those allergic to shellfish, are at risk of adverse reactions. It is important to identify and address this allergy to prevent potential complications. The other options do not directly impact the safety or effectiveness of the CT scan with contrast media. Claustrophobia can be managed with patient support, the recent use of a bronchodilator inhaler does not typically affect the CT procedure, and not being able to remove a wedding band is not a critical concern for the scan itself.

3. Mr. C is brought to the hospital with severe burns over 45% of his body. His heart rate is 124 bpm and thready, BP 84/46, respirations 24/minute and shallow. He is apprehensive and restless. Which of the following types of shock is Mr. C at highest risk for?

• A. Septic shock
• B. Hypovolemic shock
• C. Neurogenic shock
• D. Cardiogenic shock

Correct answer: B

Rationale: Mr. C, who has severe burns over 45% of his body, is at highest risk for hypovolemic shock. Burns lead to a loss of plasma volume, reducing the circulating fluid volume and impairing perfusion to vital organs and extremities. In this scenario, the signs of shock, such as increased heart rate, low blood pressure, shallow respirations, and restlessness, indicate a state of hypovolemic shock due to significant fluid loss. Septic shock (choice A) is primarily caused by severe infections, neurogenic shock (choice C) results from spinal cord injuries, and cardiogenic shock (choice D) stems from heart failure. However, in this case, the presentation aligns most closely with hypovolemic shock due to the extensive burn injury and its effects on fluid volume and perfusion.

4. 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.

5. A nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?

• A. Slow pulse rate
• B. Weight gain
• C. Decreased systolic pressure
• D. Irregular WBC lab values

Correct answer: B

Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.
