A nurse is caring for a client who is at risk for hypokalemia. Which of the following foods should be included in the client's diet?
Corn.
Cucumbers.
Asparagus.
Tomatoes.
The Correct Answer is D
Choice A rationale
Corn is a starchy vegetable that provides some nutrients but is not considered a high-potassium food source. In the management of hypokalemia, where serum potassium levels are below 3.5 mEq/L, the focus is on incorporating foods with high concentrations of the cation. While corn contains approximately 270 mg of potassium per cup, it is significantly less dense in this electrolyte compared to other vegetables. It does not provide the robust replacement needed for high-risk clients.
Choice B rationale
Cucumbers consist mostly of water and fiber but are relatively low in potassium content. One cup of sliced cucumbers provides only about 150 mg of potassium, which is insufficient for effectively raising serum levels in a client at risk for hypokalemia. While healthy for hydration, they are not the therapeutic choice for electrolyte replacement. Dietitians prioritize foods that offer a higher milligram-to-volume ratio of potassium to ensure that the patient meets the necessary daily intake goals.
Choice C rationale
Asparagus is a nutritious vegetable containing various vitamins and minerals, providing roughly 200 mg of potassium per serving. While it is better than some other low-potassium options, it still falls short of being a primary dietary recommendation for treating low potassium. Clients needing to increase their potassium intake are encouraged to consume foods that provide a more substantial boost per serving. It is a healthy addition but not the most potent choice for electrolyte management.
Choice D rationale
Tomatoes are an excellent source of potassium and are highly recommended for clients at risk for hypokalemia. A single cup of tomato juice or a large tomato can provide over 400 mg of potassium, which helps maintain serum levels within the normal range of 3.5 to 5.0 mEq/L. Increasing intake of potassium-rich foods like tomatoes helps support cardiac electrical conductivity and muscle contraction. This makes them a vital dietary component for preventing the complications of low potassium.

Correct Answer is C
Explanation
Choice A rationale
While monitoring nutritional intake is important for overall health, eating only 60 percent of breakfast is not a direct contraindication for administering antihypertensive medication. Poor appetite might be relevant if the patient were taking insulin or had significant electrolyte imbalances, but it does not typically alter the immediate safety profile of a blood pressure drug. Unless the patient is experiencing nausea or vomiting that prevents oral intake, this finding does not require urgent assessment before medication.
Choice B rationale
Reporting trouble sleeping is a common subjective finding in hospitalized patients and does not usually necessitate withholding or delaying antihypertensive therapy. While chronic sleep deprivation can influence long-term blood pressure trends, it is not an acute assessment finding that indicates a high risk for an adverse drug event. The nurse should document the sleep issue and address it later, but it does not take priority over evaluating signs of hemodynamic instability before dosing.
Choice C rationale
Dizziness when ambulating is a classic symptom of orthostatic hypotension or significantly low blood pressure. Antihypertensive medications further lower blood pressure, which could exacerbate this dizziness and increase the client's risk for falls and injury. The nurse must assess the client's current blood pressure and heart rate, perhaps performing orthostatic vitals, to determine if it is safe to proceed with the medication. This finding indicates a potential safety risk that requires immediate clinical judgment.
Choice D rationale
A urine output of 400 mL over 8 hours averages to 50 mL per hour, which is well above the minimum safe threshold of 30 mL per hour. This indicates that the client has adequate renal perfusion and kidney function at this time. Since the output is within normal limits, it does not provide a reason to delay antihypertensive administration. In fact, maintaining controlled blood pressure is essential for protecting long-term renal health and preventing hypertensive kidney damage.
Correct Answer is ["A","C"]
Explanation
Choice A rationale
Sleep deprivation significantly disrupts the regulation of neurotransmitters in the brain, particularly serotonin and dopamine. These chemicals are essential for maintaining emotional stability and a balanced mood. When a person lacks sufficient restorative sleep, the amygdala becomes hyper-reactive to negative stimuli, leading to heightened emotional responses. This neurological irritability often manifests as sudden mood swings, irritability, or increased emotional sensitivity during daily interactions and tasks.
Choice B rationale
While tension headaches are commonly associated with high levels of stress or poor posture, they are not typically classified as a primary direct physiological adverse effect of sleep deprivation itself. Although a lack of sleep can lower a person's pain threshold or increase general discomfort, the clinical literature specifically focuses on cognitive and psychological impairments. Therefore, tension headaches are considered an indirect or secondary symptom rather than a primary diagnostic indicator of sleep loss.
Choice C rationale
Chronic insomnia and prolonged sleep deprivation are heavily linked to the development or exacerbation of depression. Lack of sleep impairs the prefrontal cortex, which is responsible for executive function and emotional regulation. This impairment can lead to persistent feelings of hopelessness, loss of interest in activities, and a general decline in mental health. Long-term disruption of the circadian rhythm often precedes clinical depressive episodes in many vulnerable patients in clinical settings.
Choice D rationale
Hyperreflexia refers to overactive or overresponsive bodily reflexes, which is usually indicative of an upper motor neuron lesion or specific electrolyte imbalances rather than simple sleep deprivation. Sleep loss tends to result in delayed reaction times and diminished motor coordination rather than an exaggerated reflex response. The physiological strain of insomnia typically suppresses the nervous system's efficiency, leading to lethargy and slowed physical movements rather than the spasticity seen in hyperreflexia.
Choice E rationale
Altered taste, or dysgeusia, is not a recognized physiological consequence of inadequate sleep. Taste perception is governed by the gustatory cells in the taste buds and the cranial nerves that transmit these signals to the brain. While sleep deprivation can influence appetite and cravings for high-calorie foods due to changes in ghrelin and leptin levels, it does not physically change the sensory mechanism of taste or the ability to distinguish between different flavor profiles.
