Nursing Elites

1. A client who is mouth breathing is receiving oxygen by face mask. The nursing assistant asks the nurse why a water bottle is attached to the oxygen tubing near the wall oxygen outlet. The nurse responds that the primary purpose of the water is to:

• A. Prevent the client from getting a nosebleed
• B. Give the client added fluid by way of the respiratory tree
• C. Humidify the oxygen that is bypassing the client’s nose
• D. Prevent fluid loss from the lungs during mouth breathing

Correct answer: C

Rationale: The purpose of the water bottle is to humidify the oxygen that is bypassing the nose during mouth breathing. When a client breathes through the mouth, the oxygen delivered by the face mask bypasses the natural humidification provided by the nasal passages. Therefore, the water bottle attachment helps to add moisture to the oxygen, preventing dryness and irritation to the respiratory tract. Choices A, B, and D are incorrect. Clients breathing through the mouth are not at risk for nosebleeds, do not receive added fluid through the respiratory tree, and do not experience fluid loss from the lungs due to mouth breathing.

2. The nurse is caring for a client who is receiving an IV infusion of normal saline and notices that the infusion is not flowing. The insertion site is not inflamed or swollen. What should the nurse do first?

• A. Check the tubing for kinks or obstructions.
• B. Increase the flow rate to improve the infusion.
• C. Reinsert the IV catheter in another vein.
• D. Call the physician for further instructions.

Correct answer: A

Rationale: The correct first action for the nurse to take when an IV infusion is not flowing despite a normal insertion site is to check the tubing for kinks or obstructions. This step is crucial to ensure that there are no preventable issues impeding the flow of the IV solution. Increasing the flow rate without addressing potential obstructions could lead to complications such as infiltration. Reinserting the IV catheter in another vein should only be considered after ruling out tubing issues. Calling the physician for further instructions is not necessary at this stage as troubleshooting the tubing should be the initial intervention.

3. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?

• A. Iso-osmolar
• B. Hypo-osmolar
• C. Hyperosmolar
• D. Isotonic

Correct answer: C

Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.

4. A client with cirrhosis develops increasing pedal edema and ascites. What dietary modification is most important for the nurse to teach this client?

• A. Avoid high carbohydrate foods.
• B. Decrease intake of fat-soluble vitamins.
• C. Decrease caloric intake.
• D. Restrict salt and fluid intake.

Correct answer: D

Rationale: The correct answer is to restrict salt and fluid intake. In clients with cirrhosis presenting with pedal edema and ascites, excessive fluid retention occurs, necessitating the restriction of salt and fluid to alleviate these symptoms. Choice A, avoiding high carbohydrate foods, is not the priority in this situation. Decreasing intake of fat-soluble vitamins (Choice B) is not specifically indicated for managing edema and ascites in cirrhosis. While maintaining an appropriate caloric intake is important, decreasing caloric intake (Choice C) is not the primary focus when addressing fluid retention in cirrhosis.

5. The patient is receiving a high dose of tetracycline (Sumycin). Which laboratory values should the nurse monitor while caring for this patient?

• A. Blood urea nitrogen (BUN) and creatinine levels
• B. Complete blood counts
• C. Electrolytes
• D. Liver enzyme levels

Correct answer: A

Rationale: High doses of tetracyclines can lead to nephrotoxicity, especially when given along with other nephrotoxic drugs. Renal function tests, such as monitoring blood urea nitrogen (BUN) and creatinine levels, should be performed to assess for nephrotoxicity. Monitoring complete blood counts (choice B) is not directly related to tetracycline therapy. Checking electrolytes (choice C) is important but not the priority when monitoring for tetracycline-induced nephrotoxicity. Monitoring liver enzyme levels (choice D) is not typically indicated in the context of tetracycline therapy.
