Question 1 of 9

A client at risk for developing hyperkalemia states, 'I love fruit and usually eat it every day, but now I can't because of my high potassium level.' How should the nurse respond?

Correct Answer: C

Rationale: Rationale: Option C is correct because berries, cherries, apples, and peaches are indeed low in potassium compared to other fruits. This response acknowledges the client's love for fruits while providing suitable alternatives to manage potassium levels. By choosing these low-potassium fruits, the client can continue enjoying fruits without exacerbating hyperkalemia. Incorrect options: A: Potatoes and avocados are high in potassium, so they are not suitable substitutes. B: Cooking fruit does not significantly reduce its potassium content. D: This option lacks guidance and does not offer a solution to the client's concern about high potassium levels.

Question 2 of 9

The nurse in the medical ICU is caring for a patient who is in respiratory acidosis due to inadequate ventilation. What diagnosis could the patient have that could cause inadequate ventilation?

Correct Answer: C

Rationale: Rationale: Guillain-Barr syndrome can cause inadequate ventilation due to paralysis of the respiratory muscles. This results in respiratory acidosis. Endocarditis, multiple myeloma, and amphetamine overdose do not directly affect ventilation. Endocarditis is an infection of the heart valves, multiple myeloma is a cancer of plasma cells, and amphetamine overdose primarily affects the central nervous system and cardiovascular system, not ventilation. Therefore, Guillain-Barr syndrome is the most likely diagnosis in this case.

Question 3 of 9

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: Step 1: Chvostek's sign is a facial muscle spasm induced by tapping the facial nerve in hypocalcemia. Step 2: Hypocalcemia causes increased neuromuscular excitability, leading to Chvostek's sign. Step 3: Hyperkalemia (choice D) causes muscle weakness, not muscle spasm. Step 4: Hyponatremia (choice B) affects osmolarity, not neuromuscular excitability. Step 5: Hypermagnesemia (choice A) causes muscle weakness, not muscle spasm.

Question 4 of 9

You are making initial shift assessments on your patients. While assessing one patients peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?

Correct Answer: C

Rationale: Correct Answer: C - Infiltration Rationale: 1. Infiltration occurs when IV fluid leaks into surrounding tissues, causing edema. 2. Documenting infiltration is important for appropriate management. 3. Air emboli, phlebitis, and fluid overload are unrelated to edema around IV site. Summary of Incorrect Choices: A. Air emboli: This is a serious condition caused by air entering the bloodstream, not related to edema. B. Phlebitis: Inflammation of the vein, usually presenting with redness and pain, not edema. D. Fluid overload: Excess fluid volume in the body, leading to symptoms like shortness of breath, not edema.

Question 5 of 9

You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patients skin turgor?

Correct Answer: C

Rationale: The correct answer is C: Inelastic skin turgor is a normal part of aging. As people age, their skin loses elasticity and becomes less turgid, which can affect skin turgor assessment. Skin turgor assessment is an important indicator of hydration status, and in older adults, it is normal for the skin to be less elastic. This is due to changes in collagen and elastin fibers in the skin with aging. Choices A, B, and D are incorrect because overhydration is not common among healthy older adults, dehydration causes the skin to appear tented rather than spongy, and skin turgor can still be assessed in patients over 70, although it may be less reliable due to natural changes in skin elasticity with aging.

Question 6 of 9

Diagnostic testing has been ordered to differentiate between normal anion gap acidosis and high anion gap acidosis in an acutely ill patient. What health problem typically precedes normal anion gap acidosis?

Correct Answer: D

Rationale: The correct answer is D: Excessive administration of chloride. Normal anion gap acidosis is commonly caused by an excessive intake of chloride-containing solutions like normal saline during treatment. This leads to an increase in the plasma chloride concentration, causing a decrease in the anion gap. Metastases (A) are not typically associated with normal anion gap acidosis. Excessive potassium intake (B) would not lead to normal anion gap acidosis but rather hyperkalemia. Water intoxication (C) can lead to dilutional hyponatremia but not normal anion gap acidosis.

Question 7 of 9

The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at 125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom would you expect this patient to exhibit

Correct Answer: B

Rationale: The correct answer is B: Dilute urine. Hypokalemia can lead to kidney dysfunction, causing the kidneys to excrete more water along with electrolytes, resulting in dilute urine. This is a manifestation of the body's attempt to compensate for low potassium levels by excreting excess water. The other choices are incorrect because: A) Diarrhea is more commonly associated with hyperkalemia, not hypokalemia. C) Increased muscle tone is not a typical sign of hypokalemia; rather, hypokalemia can lead to muscle weakness or paralysis due to impaired muscle function. D) Joint pain is not a typical symptom of hypokalemia; joint pain is more commonly associated with other conditions such as arthritis or inflammation.

Question 8 of 9

While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?

Correct Answer: A

Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (B) typically presents with signs like pus, warmth, and fever. Thrombosis (C) involves a blood clot, not a palpable cord. Infiltration (D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.

Question 9 of 9

You are the surgical nurse caring for a 65-year-old female patient who is postoperative day 1 following a thyroidectomy. During your shift assessment, the patient complains of tingling in her lips and fingers. She tells you that she has an intermittent spasm in her wrist and hand and she exhibits increased muscle tone. What electrolyte imbalance should you first suspect?

Correct Answer: B

Rationale: The correct answer is B: Hypocalcemia. Following a thyroidectomy, there is a risk of damaging the parathyroid glands, leading to hypocalcemia. Symptoms such as tingling in lips and fingers, muscle spasms, and increased muscle tone are classic signs of hypocalcemia. The initial concern should be hypocalcemia due to its potential to cause serious complications such as tetany and laryngospasm. Options A, C, and D are incorrect as they do not align with the symptoms described. Hypophosphatemia may present with weakness and respiratory failure, hypermagnesemia with hypotension and respiratory depression, and hyperkalemia with muscle weakness and cardiac arrhythmias.
