Nokea
The nurse is preparing to insert a peripheral IV catheter into a patient who will require fluids and IV antibiotics.
How should the nurse always start the process of insertion?
- A. Leave one hand ungloved to assess the site.
- B. Cleanse the skin with normal saline.
- C. Ask the patient about allergies to latex or iodine.
- D. Remove excessive hair from the selected site.
Correct Answer: C
Rationale: Correct Answer: C
Rationale: Asking the patient about allergies to latex or iodine is crucial before starting the IV insertion process. This step ensures patient safety and prevents potential allergic reactions. Knowing the patient's allergies allows the nurse to select appropriate materials for the procedure, reducing the risk of complications.
Summary of Other Choices:
A: Leaving one hand ungloved is not recommended as it compromises infection control practices.
B: Cleansing the skin with normal saline is important but should come after confirming allergies to latex or iodine.
D: Removing excessive hair from the site is unnecessary and not a standard practice for starting the IV insertion process.

A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?
- A. A 34-year-old on NPO status who is receiving intravenous D5W
- B. A 50-year-old with an infection who is prescribed a sulfonamide antibiotic
- C. A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin)
- D. A 73-year-old with tachycardia who is receiving digoxin (Lanoxin)
Correct Answer: A
Rationale: The correct answer is A because intravenous D5W is a hypotonic solution that can lead to dilutional hyponatremia. D5W does not contain sodium, so it can cause a decrease in serum sodium levels. Clients on NPO status receiving D5W are at higher risk due to lack of sodium intake. Choices B, C, and D are incorrect because they do not directly contribute to hyponatremia. Sulfonamide antibiotics, ibuprofen, and digoxin are not typically associated with causing hyponatremia. Therefore, assessing the client on NPO status receiving D5W for potential hyponatremia is the priority.
A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?
- A. Furosemide (Lasix) 40 mg intravenous push
- B. Sodium bicarbonate 100 mEq diluted in 1 L of D5W
- C. Mechanical ventilation
- D. Indwelling urinary catheter
Correct Answer: B
Rationale: The correct answer is B: Sodium bicarbonate 100 mEq diluted in 1 L of D5W. In this case, the client is experiencing metabolic acidosis due to low HCO3 levels (16 mEq/L) with a low pH (7.28). Sodium bicarbonate helps correct metabolic acidosis by increasing the HCO3 levels. Furosemide (A) is a diuretic and can worsen the client's electrolyte imbalance. Mechanical ventilation (C) is not indicated for metabolic acidosis. Indwelling urinary catheter (D) does not address the underlying acid-base imbalance. Therefore, the nurse should expect the provider to order sodium bicarbonate to correct the metabolic acidosis.
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?
- A. . Cardiac rate and rhythm
- B. Skin and mucous membranes
- C. Musculoskeletal strength
- D. Level of orientation
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.
You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patients most recent laboratory reports, you note that the patients magnesium levels are high. You should prioritize assessment for which of the followin
- A. Diminished deep tendon reflexes
- B. Tachycardia
- C. Cool, clammy skin
- D. Acute flank pain
Correct Answer: A
Rationale: Step 1: High magnesium levels can lead to hypermagnesemia, which can cause decreased neuromuscular function.
Step 2: Diminished deep tendon reflexes are a sign of neuromuscular impairment, indicating potential hypermagnesemia.
Step 3: Assessing for diminished deep tendon reflexes is crucial to monitor neuromuscular function in patients with high magnesium levels.
Summary: A is correct because hypermagnesemia affects neuromuscular function. B, C, and D are incorrect as they do not directly relate to the effects of high magnesium levels.
A patient who is being treated for pneumonia starts complaining of sudden shortness of breath. An arterial
blood gas (ABG) is drawn. The ABG has the following values: pH 7.21, PaCO2 64 mm Hg, HCO3 = 24 mm Hg.
What does the ABG reflect?
- A. Respiratory acidosis
- B. Metabolic alkalosis
- C. Respiratory alkalosis
- D. Metabolic acidosis
Correct Answer: A
Rationale: The correct answer is A: Respiratory acidosis. A low pH (7.21) indicates acidosis. The elevated PaCO2 (64 mm Hg) indicates respiratory acidosis, as high CO2 levels lead to carbonic acid formation, decreasing pH. The normal HCO3 (24 mm Hg) suggests compensation for the respiratory acidosis. Other choices are incorrect as they do not align with the ABG values provided. Metabolic alkalosis (B) would have a high pH and HCO3, respiratory alkalosis (C) would have a high pH and low PaCO2, and metabolic acidosis (D) would have a low pH and HCO3.
