Nursing Elites

1. You are making initial shift assessments on your patients. While assessing one patients peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?

• A. Air emboli
• B. Phlebitis
• C. Infiltration
• D. Fluid overload

Correct answer: C

Rationale:

2. You are doing discharge teaching with a patient who has hypophosphatemia during his time in hospital. The patient has a diet ordered that is high in phosphate. What foods would you teach this patient to include in his diet? Select all that do not apply

• A. Milk
• B. Beef
• C. Poultry
• D. Liver

Correct answer: B

Rationale:

3. A nurse is caring for a client who has the following arterial blood values: pH 7.12, PaO2 56 mm Hg, PaCO2 65 mm Hg, and HCO3 22 mEq/L. Which clinical situation should the nurse correlate with these values?

• A. . Diabetic ketoacidosis in a person with emphysema
• B. Bronchial obstruction related to aspiration of a hot dog
• C. Anxiety-induced hyperventilation in an adolescen
• D. Diarrhea for 36 hours in an older, frail woman

Correct answer: A

Rationale:

4. Electrolytes:

• A. do not form when glucose is added to water.
• B. dissociate in water solutions, but do not form ions.
• C. form ions in water solutions, but do not necessarily dissociate.
• D. dissociate in water solutions and form ions in water solutions.

Correct answer: D

Rationale: The correct answer is D. Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. Choice A is incorrect because glucose does not form electrolytes when added to water. Choice B is incorrect as it states that electrolytes dissociate but do not form ions, which is inaccurate as electrolytes do form ions in water solutions. Choice C is also incorrect as it states that electrolytes form ions but may not necessarily dissociate, which goes against the definition of electrolytes that must dissociate into ions for conductivity. Therefore, choice D is the most accurate as it correctly describes that electrolytes dissociate in water solutions and form ions, highlighting the essential characteristics of electrolytes.

5. A 73-year-old man who slipped on a small carpet in his home and fell on his hip is alert and oriented; PERRLA (pupils equally round and reactive to light and accommodation) is intact, and he has come by ambulance to the emergency department (ED). Heart rate elevated, he is anxious and thirsty. A Foley catheter is in place and 40mL of urine is present. The nurse's most likely explanation for the urine output is:

• A. The man urinated prior to his arrival in the ED and will probably not need to have the Foley catheter kept in place.
• B. The man has a brain injury, lacks ADH, and needs vasopressin.
• C. The man is in heart failure and is releasing atrial natriuretic peptide, which results in decreased urine output.
• D. He is having a sympathetic reaction, which has stimulated the renin-angiotensin-aldosterone system that results in diminished urine output.

Correct answer: D

Rationale: Renin is released by the juxtaglomerular cells of the kidneys in response to decreased renal perfusion. Angiotensin-converting enzyme converts angiotensin I to angiotensin II. Angiotensin II, with its vasoconstrictor properties, increases arterial perfusion pressure and stimulates thirst. As the sympathetic nervous system is stimulated, aldosterone is released in response to an increased release of renin, which decreases urine production. Based on the nursing assessment and mechanism of injury, this is the most likely cause of the lower urine output. Choices A, B, and C are incorrect because there is no indication of urination prior to arrival, brain injury, lack of ADH, or heart failure present in the scenario provided. The symptoms and context described point more towards a physiological response related to the sympathetic nervous system and the renin-angiotensin-aldosterone system rather than the other conditions mentioned.
