ATI Fluid Electrolyte and Acid-Base Regulation Questions

Question 1 of 5

. A nurse assesses a client with diabetes mellitus who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.36, PaO2 98 mm Hg, PaCO2 33 mm Hg, and HCO3 18 mEq/L. Which manifestation should the nurse identify as an exam

Correct Answer: A

Rationale: The correct answer is A: Increased rate and depth of respirations. In this case, the client's arterial blood gas values show a pH within normal range (7.36), PaCO2 below normal (33 mm Hg), and HCO3 below normal (18 mEq/L), indicating a metabolic acidosis. To compensate for the acidosis, the client will hyperventilate, leading to increased rate and depth of respirations to blow off excess CO2 and attempt to normalize the pH. Options B, C, and D are incorrect because increased urinary output, thirst, hunger, and release of acids from the kidneys are not direct compensatory mechanisms for metabolic acidosis.

Question 2 of 5

You are caring for a patient with a secondary diagnosis of hypermagnesemia. What assessment finding would be most consistent with this diagnosis?

Correct Answer: D

Rationale: The correct answer is D: Shallow respirations. Hypermagnesemia can lead to respiratory depression due to its inhibitory effect on the central nervous system. Shallow respirations are a common respiratory manifestation of hypermagnesemia. Hypertension (choice A) is not typically associated with hypermagnesemia. Kussmaul respirations (choice B) are deep, rapid breathing patterns seen in metabolic acidosis, not hypermagnesemia. Increased deep tendon reflexes (DTRs) (choice C) are more indicative of hypomagnesemia, as magnesium deficiency can lead to hyperexcitability of nerves and muscles, resulting in increased DTRs.

Question 3 of 5

A nurse assesses a client who is experiencing an acid-base imbalance. The clients arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3 19 mEq/L. Which assessment should the nurse perform first?

Correct Answer: A

Rationale: The correct answer is A: Cardiac rate and rhythm. In an acid-base imbalance, the pH is below the normal range indicating acidosis. The nurse should assess the cardiac rate and rhythm first because acidosis can have negative effects on the cardiovascular system. Acidosis can lead to arrhythmias and decreased cardiac output. Monitoring the cardiac rate and rhythm is crucial to detect any cardiac complications early. Choices B, C, and D are not the priority in this situation as they are not directly impacted by acid-base imbalances.

Question 4 of 5

A nurse assesses a client who is admitted for treatment of fluid overload. Which manifestations should the nurse expect to find? (Select all that do not apply.)

Correct Answer: C

Rationale: Step 1: Fluid overload leads to increased fluid volume in the body, causing skin to appear pale, cool, and clammy due to poor circulation. Step 2: "Warm and pink skin" is not a typical manifestation of fluid overload. Step 3: Therefore, the correct answer is C. Summary: A: Increased pulse rate - Possible in fluid overload due to increased volume causing increased workload on the heart. B: Distended neck veins - Common in fluid overload due to increased venous pressure. C: Warm and pink skin - Incorrect, as skin is usually pale, cool, and clammy. D: Skeletal muscle weakness - Not directly related to fluid overload.

Question 5 of 5

You are caring for a patient who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. During your assessment, you note the patient complains of a new onset of weakness with abdominal pain. Further assessment suggests that the patient likely has a fluid volume deficit. You should recognize that this patient may be experiencing what electrolyte imbalance?

Correct Answer: D

Rationale: The correct answer is D: Hypercalcemia. Bone metastases in lung cancer can lead to increased release of calcium into the blood, causing hypercalcemia. The patient's symptoms of weakness and abdominal pain are consistent with hypercalcemia. Hypernatremia (choice A) is unlikely as the symptoms do not align with high sodium levels. Hypomagnesemia (choice B) and hypophosphatemia (choice C) are less likely as they are not typically associated with bone metastases in lung cancer. In summary, the patient's presentation of weakness and abdominal pain in the setting of lung cancer with bone metastases points to hypercalcemia as the most likely electrolyte imbalance.

The community health nurse is performing a home visit to an 84-year-old woman recovering from hip surgery. The nurse notes that the woman seems uncharacteristically confused and has dry mucous membranes. When asked about her fluid intake, the patient states, I stop drinking water early in the day because it is just too difficult to get up during the night to go to the bathroom. What would be the nurses best response?
A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume.
