A nurse is caring for a 58-year-old client who has a low oxygen saturation. The nurse is reviewing the client's data to create a plan of care. Complete the diagram by drawing arrows to connect the condition and two parameters the nurse should monitor to assess the client's progress.
Low oxygen saturation -> Respiratory rate and heart rate
Low oxygen saturation -> Blood pressure and temperature
Low oxygen saturation -> Lung sounds and chest expansion
Low oxygen saturation -> Hemoglobin and hematocrit
The Correct Answer is C
Choice A reason: Respiratory rate and heart rate are not specific indicators of oxygen saturation. They can be affected by many other factors, such as pain, anxiety, or dehydration.
Choice B reason: Blood pressure and temperature are not directly related to oxygen saturation. They can be influenced by other conditions, such as infection, inflammation, or shock.
Choice C reason: Lung sounds and chest expansion are relevant parameters to monitor for a client with low oxygen saturation. They can indicate the presence of respiratory problems, such as pneumonia, asthma, or atelectasis, that can impair gas exchange and oxygen delivery.
Choice D reason: Hemoglobin and hematocrit are measures of red blood cell count and volume. They can affect the oxygen-carrying capacity of the blood, but they are not directly affected by oxygen saturation. They can be altered by other factors, such as bleeding, dehydration, or anemia.

Correct Answer is B
Explanation
Choice A reason: Hyperkalemia is not the correct answer. Hyperkalemia is a high level of potassium in the blood. Corticosteroids do not cause hyperkalemia, but rather hypokalemia. Hyperkalemia may be caused by other factors such as renal failure, acidosis, or potassium-sparing diuretics.
Choice B reason: Hypokalemia is the correct answer. Hypokalemia is a low level of potassium in the blood. Corticosteroids can cause hypokalemia by increasing the excretion of potassium and sodium in the urine. Hypokalemia can cause muscle weakness, cramps, arrhythmias, and digoxin toxicity.
Choice C reason: Hypermagnesemia is not the correct answer. Hypermagnesemia is a high level of magnesium in the blood. Corticosteroids do not affect magnesium levels. Hypermagnesemia may be caused by other factors such as renal failure, excessive antacid use, or magnesium-containing laxatives.
Choice D reason: Hypomagnesemia is not the correct answer. Hypomagnesemia is a low level of magnesium in the blood. Corticosteroids do not affect magnesium levels. Hypomagnesemia may be caused by other factors such as malnutrition, alcoholism, or diuretic use.
Correct Answer is C
Explanation
The correct answer is c. 2,525 mL.
Choice A reason:
1,350 mL is calculated by considering only the lactated Ringer’s IV intake. The calculation is as follows:
- Lactated Ringer’s IV at 150 mL/hr for 9 hr: 150 mL/hr × 9 hr = 1,350 mL. This option does not include the intake from cefazolin, packed RBCs, sodium chloride boluses, or famotidine.
Choice B reason:
1,600 mL is not a correct calculation based on the given intake. This value does not accurately sum up any combination of the provided intake components.
Choice C reason:
2,525 mL is the correct total intake. The detailed calculation is:
- Lactated Ringer’s IV at 150 mL/hr for 9 hr: 150 mL/hr × 9 hr = 1,350 mL.
- Cefazolin in 100 mL of 0.9% sodium chloride: 100 mL.
- Two units of packed RBCs: 275 mL + 250 mL = 525 mL.
- Two IV bolus infusions of 250 mL of 6.0% sodium chloride: 250 mL + 250 mL = 500 mL.
- Famotidine in 50 mL of 0.9% sodium chloride: 50 mL.
Adding these together: 1,350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2,525 mL.
Choice D reason:
2,100 mL is not a correct calculation based on the given intake. This value does not accurately sum up any combination of the provided intake components.
