CHA Final Exam Practice Questions and
Answers (100% Pass)
While reviewing a client's lab results, a nurse notes a serum calcium level
of 8.0 mg/dL. Which of the following actions should the nurse take?
a. Implement seizure precautions
b. Administer Phosphate
c. Initiate diuretic therapy
d. Prepare the client for hemodialysis - Answer✔️✔️-a. Implement seizure
precautions
The client is at risk for seizures due to low excitation threshold as a result
of a decreased calcium level. The nurse should initiate seizure precautions
to prevent injury
A nurse is preparing to administer oral potassium for a client who has a
potassium level of 5.5 mEq/L. Which of the following actions should the

c. Withhold the medication.
d. Monitor for paresthesia - Answer✔️✔️-c. Withhold the medication.
The greatest risk to the client is bradycardia, hypotension, and life-
threatening cardiac complications due to hyperkalemia, defined as a
potassium level above 5.0 mEq/L. Therefore, the nurse's priority action is
to withhold the oral potassium and notify the provider
A nurse is reviewing the lab report of a client who has fluid volume excess.
Which of the following lab values should the nurse expect?
a. Hemoglobin 20 g/dL
b. Hematocrit 34%
c. BUN 25 mg/dL
d. Urine specific gravity 1.050 - Answer✔️✔️-b. Hematocrit 34%
The nurse should identify that a client who has fluid volume excess can
have a hematocrit level that is below the expected reference range of 37 to
47% for females or 42 to 52% for males. Fluid volume excess can cause
hemodilution and a decreased hematocrit level.
A nurse is assessing a client who has respiratory acidosis. Which of the
following findings should the nurse expect?

a. Confusion
b. Peripheral edema
c. Facial flushing
d. Hyperreflexia - Answer✔️✔️-a. Confusion
A client who has respiratory acidosis will experience confusion from a lack
of cerebral perfusion. If acidosis is not reversed, the client's level of
consciousness will decrease and coma may occur.
A nurse is teaching nutritional strategies to a client who has low serum
calcium level and an allergy to milk. Which of the following statements by
the client indicates an understanding of the teaching?
a. "I will eat more cheese because I can't drink milk."
b. "I need to avoid foods with vitamin D because I am allergic to milk."
c. "I will stop taking my calcium supplements if they irritate my stomach."

d. "I will add broccoli and kale to my diet." - Answer✔️✔️-d. "I will add
broccoli and kale to my diet."
The nurse should recommend that the client consume broccoli and kale,
which are good sources of calcium, as alternatives to dairy products.
A nurse is reviewing ABG results for four clients. Which of the following
findings should the nurse identify as metabolic acidosis?
a. pH 7.51, PaO2 94 mm Hg, PaCO2 38 mm Hg, HCO3- 29 mEq/L
b. pH 7.48, PaO2 89 mm Hg, PaCO2 30 mm Hg, HCO3- 24 mEq/L
c. pH 7.36, PaO2 77 mm Hg, PaCO2 52 mm Hg, HCO3- 26 mEq/L
d. pH 7.26, PaO2 84 mm Hg, PaCO2 38 mm Hg, HCO3- 20 mEq/L -
Answer✔️✔️-d. pH 7.26, PaO2 84 mm Hg, PaCO2 38 mm Hg, HCO3- 20
mEq/L
A pH below 7.35 is an indication of acidosis. HCO3- below 22 mEq/L is an
indication of metabolic acidosis.
