ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse teaches a client who is being discharged home with a peripherally inserted central catheter (PICC). Which statement should the nurse include in this clients teaching?

Correct answer: A

Rationale:

2. The healthcare professional working in the PACU is aware that which of the following procedures may contribute to extracellular losses?

Correct answer: C

Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery as it involves opening the abdominal cavity, potentially leading to significant fluid losses. Choices A, B, and D do not typically result in substantial extracellular losses compared to abdominal surgery.

3. A nurse is taking care of a 65-year-old female patient in a medical-surgical unit who is in renal failure; during the assessment, the patient complains of tingling in her lips and fingers. When the nurse takes her blood pressure, she has a spasm in her wrist and hand. The nurse suspects:

Correct answer: B

Rationale: The patient's symptoms of tingling in the lips and fingers along with the wrist and hand spasm are indicative of tetany, a characteristic manifestation of hypocalcemia. Hypocalcemia and hypomagnesemia can present with sensations of tingling in the extremities and around the mouth. The spasm in the wrist and hand when taking blood pressure could be due to slight ischemia of the ulnar nerve, further supporting the suspicion of hypocalcemia in this patient. Hypophosphatemia, hypermagnesemia, and hyperkalemia do not typically present with these specific symptoms and manifestations.

4. 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:

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.

5. The nurse is assessing the patient for the presence of a Chvosteks sign. What electrolyte imbalance would a positive Chvosteks sign indicate?

Correct answer: C

Rationale:
