1. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?
- A. Ca
- B. K
- C. Na
- D. Cl
Correct answer: B
Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.
2. A client is going to have an endoscopy performed. Which of the following is not a probable reason for an endoscopy procedure?
- A. Aspiration noted on a honey-thick diet
- B. Pain felt during a bowel movement
- C. Pain felt in the left upper quadrant
- D. Right shoulder pain
Correct answer: B
Rationale: The correct answer is 'Pain felt during a bowel movement.' Endoscopy is used to examine the upper gastrointestinal tract, which includes the esophagus, stomach, and duodenum. Pain during a bowel movement would suggest an issue in the lower gastrointestinal tract, which is typically examined with a colonoscopy. Choices A, C, and D are not probable reasons for an endoscopy procedure as they relate to symptoms in the upper gastrointestinal tract or are not specific to gastrointestinal issues. Aspiration noted on a honey-thick diet could indicate a risk of aspiration pneumonia related to swallowing difficulties, which can be assessed through an endoscopy. Pain felt in the left upper quadrant may be related to conditions like gastritis or peptic ulcers that can be investigated using an endoscopy. Right shoulder pain can be a referred pain from conditions like gallbladder disease that can also be evaluated with an endoscopy.
3. The client has jaundice, elevated liver enzymes, and an elevated serum bilirubin. What color urine does the nurse expect to find?
- A. Pink-tinged
- B. Straw-colored
- C. Clear
- D. Dark amber
Correct answer: D
Rationale: The correct answer is dark amber. In jaundice, the elevated bilirubin levels are excreted in the urine, giving it a dark amber color. Choices A, B, and C are incorrect because in jaundice, the urine typically appears dark amber due to the presence of elevated bilirubin, not pink-tinged, straw-colored, or clear.
4. A healthcare professional is reviewing a patient's arterial blood gas values. Which of the following conditions apply under the following values? pH- 7.49 Bicarbonate ion 24 mEq/dl PaCO2 - 31 mmHg PaO2 - 52 mmHg FiO2 - 0.22
- A. respiratory acidosis
- B. respiratory alkalosis
- C. metabolic acidosis
- D. metabolic alkalosis
Correct answer: B
Rationale: The given blood gas values indicate respiratory alkalosis. A high pH and low PaCO2 level are consistent with respiratory alkalosis. In this scenario, no compensation for the alkalosis is noted, ruling out metabolic acidosis or alkalosis. Metabolic conditions would usually involve changes in bicarbonate levels, which remain within the normal range in this case.
5. A newborn baby exhibits a reflex that includes hand opening, abducted, and extended extremities following a jarring motion. Which of the following correctly identifies the reflex?
- A. ATNR reflex
- B. Startle reflex
- C. Grasping reflex
- D. Moro reflex
Correct answer: D
Rationale: The Moro reflex, also known as the startle reflex, is the correct answer. This reflex is characterized by the baby's response to a sudden head movement or loud noise, causing them to open their hands, extend their arms, and then bring them back towards their body. The characteristics mentioned in the question - hand opening, abducted, and extended extremities following a jarring motion - align with the Moro reflex. The asymmetrical tonic neck reflex (ATNR) involves the head turning to one side with extension of the same side's arm and leg, not the described characteristics. The grasping reflex involves the baby's response to touch on the palm, causing them to grasp an object. While the Moro reflex is often referred to as the startle reflex due to its response to sudden stimuli, the specific characteristics described in the question match the Moro reflex.
