The nurse includes in the instructions to a 50-year-old male client taking estrogens as treatment for prostate cancer that he may develop?

Choice A rationale

Decreasing fluid intake can lead to dehydration, which exacerbates fatigue by impairing cellular metabolic processes and reducing blood volume, thus decreasing oxygen and nutrient delivery to tissues. Optimal hydration is crucial for maintaining cellular function, electrolyte balance, and overall energy levels, as it supports efficient metabolic waste removal and nutrient transport, thereby mitigating fatigue associated with radiation therapy. Normal fluid intake for an adult is typically 2.5-3.5 liters per day.

Choice B rationale

Planning 4-5 hours of daytime rest can disrupt normal nocturnal sleep patterns, leading to fragmented sleep and an exacerbation of fatigue. Excessive daytime napping can alter the circadian rhythm, making it difficult to achieve restorative sleep at night, which is essential for cellular repair, hormone regulation, and energy restoration. Short, strategic naps of 20-30 minutes are generally more beneficial to alleviate fatigue without interfering with nighttime sleep.

Choice C rationale

Avoiding between-meal snacks can lead to prolonged periods without caloric intake, resulting in hypoglycemia and depleted energy reserves, which significantly contribute to fatigue. Regular, small, nutrient-dense snacks help maintain stable blood glucose levels, providing a continuous supply of energy for metabolic processes and preventing the energy troughs that intensify fatigue. Adequate nutrition is vital for cellular energy production during radiation therapy.

Choice D rationale

Prioritizing activities from important to least important allows the client to conserve energy for essential tasks, preventing overexertion and managing fatigue effectively. This strategy, known as energy conservation, involves pacing activities, delegating non-essential tasks, and incorporating rest periods, thereby optimizing energy utilization and minimizing the physiological and psychological burden of fatigue commonly experienced during radiation therapy.

Choice A rationale

Hypophosphatemia, a low level of phosphate, is not typically expected in tumor lysis syndrome (TLS). Instead, the rapid breakdown of tumor cells releases intracellular components, including large amounts of phosphate, leading to hyperphosphatemia, not hypophosphatemia.

Choice B rationale

Hypokalemia, a low level of potassium, is not expected in tumor lysis syndrome. The lysis of tumor cells releases significant quantities of intracellular potassium into the bloodstream, leading to hyperkalemia, which is a life-threatening electrolyte imbalance due to its impact on cardiac function.

Choice C rationale

Hypouricemia, a low level of uric acid, is not expected in tumor lysis syndrome. The rapid catabolism of purines from lysed tumor cells leads to a massive production of uric acid, resulting in hyperuricemia. This can precipitate in the renal tubules, causing acute kidney injury.

Choice D rationale

Hyperkalemia is a hallmark laboratory finding in tumor lysis syndrome. The rapid destruction of large numbers of cancer cells releases their intracellular contents into the bloodstream. Since potassium is abundant within cells, its release leads to a significant elevation in serum potassium levels. Normal potassium levels are 3.5 to 5.0 mEq/L.
