Nursing Elites

1. What is the purpose of the cuff in a Tracheostomy tube?

• A. Separate the upper and lower airway
• B. Separate trachea from the esophagus
• C. Separate the larynx from the nasopharynx
• D. Secure the placement of the tube

Correct answer: B

Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.

2. Angie is a disoriented client who frequently falls from the bed. As her nurse, which of the following is the best nursing intervention to prevent future falls?

• A. Tell Angie not to get up from bed unassisted
• B. Put the call bell within her reach
• C. Put bedside commode at the bedside to prevent Angie from getting up
• D. Put the bed in the lowest position ever

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. A nurse is providing teaching to an obese client who has gestational diabetes and is at 25 weeks of gestation. Which of the following statements made by the client indicates a need for further teaching?

• A. This does not mean that my baby will have this disease.
• B. This means that I will have diabetes for the rest of my life.
• C. If I feel dizzy, I should drink six ounces of a non-diet soda.
• D. Being obese might be one reason why I developed diabetes.

Correct answer: B

Rationale: The statement 'This means that I will have diabetes for the rest of my life' indicates a need for further teaching. Gestational diabetes often resolves after pregnancy, although it does indicate a higher risk for developing type 2 diabetes in the future. The other choices are correct or provide appropriate information: A) Understanding that gestational diabetes does not mean the baby will have the disease is accurate. C) Advising to drink non-diet soda if feeling dizzy is incorrect and potentially harmful due to the sugar content. D) Recognizing that obesity can be a risk factor for developing diabetes is a valid statement.

4. What type of diet would most likely benefit a patient with cystic fibrosis?

• A. Low sodium
• B. Low fat
• C. Clear liquid
• D. High calorie, high protein

Correct answer: D

Rationale: Patients with cystic fibrosis often have malabsorption issues, leading to increased energy needs. A high-calorie, high-protein diet is recommended to help meet these needs, support growth, and maintain overall health. Choices A, B, and C do not address the specific dietary requirements associated with cystic fibrosis, making them less beneficial for these patients.

5. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.
