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 admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?

• A. Chest x-ray shows no upper lobe infiltrates.
• B. TB medications have been taken for 6 months.
• C. Mantoux testing shows an induration of 10 mm.
• D. Three sputum smears for acid-fast bacilli are negative.

Correct answer: D

Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.

3. Which fact about diabetes is true?

• A. Only children get type 1 diabetes.
• B. Only adults get type 2 diabetes.
• C. Children and adults can have type 1 diabetes.
• D. Both A and B

Correct answer: C

Rationale: The correct answer is that children and adults can have type 1 diabetes. Although type 1 diabetes is sometimes known as 'childhood diabetes,' it can affect individuals of any age. Type 1 diabetes is not limited to children. While type 2 diabetes is often associated with adults, children can also develop it, especially due to factors like obesity. Choices A and B are incorrect because diabetes is not exclusive to either children or adults; both types of diabetes can affect individuals across different age groups.

4. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.

5. The clinic nurse reviews the record of an infant and notes that the primary health care provider (PHCP) has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek health care for the infant?

• A. Diarrhea
• B. Projectile vomiting
• C. Regurgitation of feedings
• D. Constipation

Correct answer: C

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is characterized by the absence of ganglion cells in the rectum and other parts of the affected intestine. Clinical manifestations of Hirschsprung's disease include chronic constipation with pellet-like or ribbon-like foul-smelling stools, delayed or absent passage of meconium in the neonatal period, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive. In the case of an infant with suspected Hirschsprung's disease, regurgitation of feedings is a sign that may have led the mother to seek healthcare. This symptom can be associated with the bowel dysfunction and obstruction seen in Hirschsprung's disease. Options A, B, and D are not typically associated with Hirschsprung's disease. Diarrhea is not a common symptom, projectile vomiting is not a typical presentation, and constipation, while a symptom of the disease, is not the sign that would most likely prompt a visit to seek healthcare in an infant suspected of having Hirschsprung's disease.
