A client with acute renal injury (AKI) weighs 110.3 pounds (50 kg) and has a potassium level of 6.7 mEq/L (6.7 mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?
Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]
Sodium polystyrene sulfonate 15 grams by mouth.
Sevelamer one tablet by mouth.
Calcium acetate one tablet by mouth.
Epoetin alfa, recombinant 2,500 units subcutaneously.
The Correct Answer is A
Choice A reason: Sodium polystyrene sulfonate is a medication that binds to excess potassium in the gastrointestinal tract and removes it from the body through feces. It is used to treat hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can cause cardiac arrhythmias and muscle weakness, and it is a common complication of AKI. Therefore, this medication should be administered first to lower the potassium level and prevent life-threatening complications.
Choice B reason: Sevelamer is a medication that binds to phosphorus in the gastrointestinal tract and removes it from the body through feces. It is used to treat hyperphosphatemia, which is a high level of phosphorus in the blood. Hyperphosphatemia can cause bone loss and soft tissue calcification, and it is a common complication of chronic kidney disease (CKD). However, it is not an urgent issue in AKI, and it does not affect the potassium level.
Choice C reason: Calcium acetate is a medication that also binds to phosphorus in the gastrointestinal tract and removes it from the body through feces. It has the same effect and indication as sevelamer, but it also provides calcium supplementation. However, it is not an urgent issue in AKI, and it does not affect the potassium level.
Choice D reason: Epoetin alfa, recombinant is a medication that stimulates the production of red blood cells in the bone marrow. It is used to treat anemia, which is a low level of hemoglobin or red blood cells in the blood. Anemia can cause fatigue, weakness, and shortness of breath, and it is a common complication of CKD and AKI. However, it is not an urgent issue in AKI, and it does not affect the potassium level.

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: This is correct because performing a bedside pregnancy test is the intervention that should be implemented immediately by the nurse. This is to confirm or rule out pregnancy and inform the surgical team of any possible risks or complications that may affect the client or the fetus.
Choice B reason: This is incorrect because continuing with surgery as scheduled is not an appropriate intervention without verifying the pregnancy status of the client. Surgery may pose serious threats to both maternal and fetal health, such as bleeding, infection, anesthesia complications, or miscarriage.
Choice C reason: This is incorrect because calculating gestation from last menstrual cycle is not an accurate or reliable method of determining pregnancy. The menstrual cycle can vary widely among women and may be affected by various factors such as stress, illness, or medication.
Choice D reason: This is incorrect because notifying the surgical team to cancel the surgery is not a necessary intervention unless pregnancy is confirmed. Appendicitis is a medical emergency that requires prompt surgical treatment to prevent rupture, peritonitis, or sepsis.
