A client who received 6 units of packed red blood cells 3 days ago for a lower gastrointestinal (GI) bleed is now displaying signs of shortness of breath with occasional stridor and is reporting muscle cramping.
Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]
Magnesium [Adult: 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L)]
Calcium [9 to 10.5 mg/dL (2.3 to 2.6 mmol/L)]
Sodium (136 to 145 mEq/L (136 to 145 mmol/L)]
Which serum laboratory value should the nurse immediately report to the healthcare provider?
Potassium 4.7 mEq/L (4.70 mmol/L).
Magnesium 2.1 mEq/L (0.86 mmol/L).
Calcium 6.5 mg/dL (1.63 mmol/L).
Sodium 135 mEq/L (135 mmol/L).
The Correct Answer is C
Choice A reason: Potassium 4.7 mEq/L (4.70 mmol/L) is within the normal reference range of 3.5 to 5 mEq/L (3.5 to 5 mmol/L). Potassium is an electrolyte that helps regulate the balance of fluids and acids in the body, as well as the function of nerves and muscles. A high potassium level (hyperkalemia) can cause muscle weakness, irregular heartbeat, and cardiac arrest. A low potassium level (hypokalemia) can cause muscle cramps, fatigue, and arrhythmias.
Choice B reason: Magnesium 2.1 mEq/L (0.86 mmol/L) is within the normal reference range of 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L). Magnesium is an electrolyte that helps regulate the activity of enzymes, muscles, and nerves, as well as the balance of calcium and potassium in the body. A high magnesium level (hypermagnesemia) can cause nausea, vomiting, flushing, muscle weakness, and respiratory depression. A low magnesium level (hypomagnesemia) can cause muscle twitching, tremors, seizures, and cardiac arrhythmias.
Choice C reason: Calcium 6.5 mg/dL (1.63 mmol/L) is below the normal reference range of 9 to 10.5 mg/dL (2.3 to 2.6 mmol/L). Calcium is an electrolyte that helps regulate the function of muscles, nerves, bones, and blood clotting. A high calcium level (hypercalcemia) can cause nausea, vomiting, constipation, confusion, kidney stones, and bone pain. A low calcium level (hypocalcemia) can cause muscle spasms, cramps, tingling, numbness, and stridor (a high-pitched sound when breathing). **This is a critical value that should be immediately reported to the healthcare provider**, as it can indicate a serious condition such as acute pancreatitis, sepsis, or massive blood transfusion.
Choice D reason: Sodium 135 mEq/L (135 mmol/L) is slightly below the normal reference range of 136 to 145 mEq/L (136 to 145 mmol/L). Sodium is an electrolyte that helps regulate the balance of fluids and acids in the body, as well as the function of nerves and muscles. A high sodium level (hypernatremia) can cause thirst, dry mouth, confusion, seizures, and coma. A low sodium level (hyponatremia) can cause headache, nausea, vomiting, fatigue, muscle weakness, and confusion.

Correct Answer is []
Explanation
Focused assesment area : Neurological
The correct answer is B. Speaks in short sentences.
Choice A: Drinks with repetitive cough. This is an incorrect answer because it indicates that the patient has difficulty swallowing, which is a common complication of ischemic stroke. Swallowing problems can lead to aspiration pneumonia, dehydration, and malnutrition. Therefore, this finding does not indicate effective early intervention for ischemic stroke¹.
Choice B: Speaks in short sentences. This is a correct answer because it indicates that the patient's speech has improved from being garbled to being intelligible. Speech impairment is a common symptom of ischemic stroke, especially when the left hemisphere of the brain is affected. Early intervention with thrombolytic therapy or mechanical thrombectomy can restore blood flow to the affected brain tissue and reduce the extent of damage². Therefore, this finding indicates effective early intervention for ischemic stroke.
Choice C: Decorticate posturing. This is an incorrect answer because it indicates that the patient has severe brain damage and is in a state of coma. Decorticate posturing is a type of abnormal posture that occurs when the upper limbs flex and the lower limbs extend in response to pain or stimulation. It indicates damage to the cerebral hemispheres or the internal capsule³. Therefore, this finding does not indicate effective early intervention for ischemic stroke.
Focused assesment area : Muscoskeletal
The correct answer is B. Ambulates with a walker.
Choice A: Flaccidity of left arm. This is an incorrect answer because it indicates that the patient has weakness or paralysis of the left arm, which is a common symptom of ischemic stroke. Flaccidity is the absence of muscle tone or resistance to passive movement. It indicates damage to the motor cortex or the corticospinal tract. Therefore, this finding does not indicate effective early intervention for ischemic stroke.
Choice B: Ambulates with a walker. This is a correct answer because it indicates that the patient has regained some mobility and independence after the ischemic stroke. Ambulation is the ability to walk or move from one place to another. Early intervention with physical therapy and rehabilitation can help improve the patient's functional recovery and prevent complications such as deep vein thrombosis, pressure ulcers, and contractures. Therefore, this finding indicates effective early intervention for ischemic stroke.
Choice C: Passive range of motion on left leg. This is an incorrect answer because it indicates that the patient has limited or no voluntary movement of the left leg, which is another common symptom of ischemic stroke. Passive range of motion is the movement of a joint or limb by an external force, such as a therapist or a caregiver. It indicates damage to the motor cortex or the corticospinal tract. Therefore, this finding does not indicate effective early intervention for ischemic stroke.
Focused assesment area : Psychosocial
The correct answer is B. Tearful sharing of stories.
Choice A: Fits of laughter. This is an incorrect answer because it indicates that the patient has inappropriate emotional responses, which is a common complication of ischemic stroke. Inappropriate emotional responses are sudden and uncontrollable episodes of laughing or crying that are out of context or disproportionate to the situation. They indicate damage to the brain regions that regulate emotions, such as the frontal lobe, the thalamus, or the brainstem. Therefore, this finding does not indicate effective early intervention for ischemic stroke.
Choice B: Tearful sharing of stories. This is a correct answer because it indicates that the patient has improved social and emotional functioning after the ischemic stroke. Tearful sharing of stories is a normal and healthy way of expressing emotions and coping with stress. It also shows that the patient has preserved memory and language skills, which are often impaired by ischemic stroke. Early intervention with psychological support and counseling can help the patient deal with the emotional impact of stroke and improve their quality of life. Therefore, this finding indicates effective early intervention for ischemic stroke.
Choice C: Angry outburst. This is an incorrect answer because it indicates that the patient has mood disturbances, which is another common complication of ischemic stroke. Mood disturbances are changes in the patient's emotional state, such as depression, anxiety, irritability, or aggression. They indicate damage to the brain regions that regulate mood, such as the frontal lobe, the amygdala, or the hippocampus. Therefore, this finding does not indicate effective early intervention for ischemic stroke.
Correct Answer is A
Explanation
Choice A reason: Gastroccult positive emesis indicates the presence of blood in the vomit, which is a sign of a serious complication such as anastomotic leak, ulcer, or bleeding. The nurse should notify the physician and monitor the client's vital signs and hemoglobin level.
Choice B reason: Strong foul smelling flatus is a common side effect of BPD, which involves bypassing a large portion of the small intestine and creating a connection between the stomach and the colon. This results in malabsorption and bacterial overgrowth, which produce gas and odor.
Choice C reason: Complaint of poor night vision is a sign of vitamin A deficiency, which can occur after BPD due to reduced absorption of fat-soluble vitamins. The nurse should advise the client to take vitamin supplements and eat foods rich in vitamin A, such as carrots, sweet potatoes, and spinach.
Choice D reason: Loose bowel movements are another common side effect of BPD, which causes diarrhea and steatorrhea (fatty stools). The nurse should encourage the client to drink fluids with electrolytes and avoid foods that worsen diarrhea, such as greasy, spicy, or sugary foods.
