🔷 Syndrome of inappropriate antidiuretic hormone (SIADH) causes excessive release of antidiuretic hormone (ADH), which leads to abnormal water retention by the kidneys.

🔷 Because water is retained, the client typically has decreased urine output with concentrated urine rather than large volumes of dilute urine.

🔷 The retained free water dilutes serum sodium, producing hyponatremia, which is a hallmark finding in SIADH. The Merck Manual describes SIADH as characterized by euvolemic hyponatremia with impaired water excretion.

🔷 Clients may also develop manifestations related to low sodium such as headache, confusion, lethargy, seizures, or worsening neurologic changes if hyponatremia becomes severe.

🔷 For exam questions, SIADH = retain water, low urine output, low sodium is the classic pattern.

🔹 Increased thirst with dry mucous membranes is incorrect because those findings suggest fluid volume deficit/dehydration, not water retention. SIADH causes dilutional problems, not classic dehydration.

🔹 Polyuria and dilute urine is incorrect because that pattern is more consistent with diabetes insipidus, which is essentially the opposite of SIADH. In SIADH, urine tends to be reduced and concentrated.

🔹 Hypernatremia and dehydration is incorrect because SIADH causes hyponatremia, not hypernatremia. Hypernatremia is more consistent with free-water loss disorders.

🟣 Hypothyroidism is associated with a slowed metabolic state, so clients commonly develop fatigue, decreased energy, and lethargy.

🟣 A “mask-like” face may occur because of myxedematous facial puffiness and reduced facial animation, which are classic hypothyroid features.

🟣 Hypothermia (or cold intolerance) is consistent with decreased metabolic heat production, another hallmark manifestation of reduced thyroid hormone activity.

🟣 Additional common findings may include weight gain, bradycardia, constipation, dry skin, and slowed reflexes, all reflecting generalized metabolic slowing. The NIH notes symptoms such as fatigue, cold intolerance, and puffy face are common in hypothyroidism.

🟣 For exam questions, slow body systems = hypothyroidism is the pattern to recognize.

🔹 Weight loss, diarrhea, and nervousness is incorrect because those findings are more consistent with hyperthyroidism, where metabolism is increased rather than slowed. They do not fit classic hypothyroidism.

🔹 Increased appetite, restlessness, and insomnia is incorrect because these also reflect hypermetabolic stimulation, not reduced thyroid function. Hypothyroid clients more often have fatigue and slowed activity.

🔹 Tachycardia, heat intolerance, and weight loss is incorrect because these are classic hyperthyroidism manifestations. Hypothyroidism more often causes bradycardia, cold intolerance, and weight gain.

🔷 The prostate is relatively difficult for many antibiotics to penetrate, so treatment for acute bacterial prostatitis often needs to continue longer than for many other infections. Sources describing prostatitis treatment note that prolonged therapy is used because achieving and maintaining effective antibiotic levels in prostatic tissue can be challenging.

🔷 This explanation helps the client understand that the longer course is not arbitrary. It is meant to fully eradicate infection and reduce the chance of persistence or recurrence.

🔷 The nurse should reinforce that stopping early can allow infection to remain in the prostate even if symptoms improve quickly.

🔷 This is the best answer because it explains the anatomic/pharmacologic reason for extended therapy.

🔷 In short: limited penetration into the prostate = longer antibiotic course.

🔹 “Older adults are at greater risk for reinfection...” is incorrect because age alone is not the reason antibiotics are extended here. The key issue is prostatic penetration, not simply older age.

🔹 “Antibiotic resistance is the main concern... so antibiotics must be stopped early...” is incorrect because stopping early can worsen treatment failure. Standard teaching is to complete the prescribed course, not shorten it.

🔹 “It’s not necessary to complete the full course...” is incorrect because symptom improvement does not guarantee eradication of infection. The client should be taught to finish therapy as prescribed.

🟢 Glucagon is the hormone that stimulates glycogenolysis in the liver, which raises blood glucose levels. Endotext and other endocrine references describe glucagon as increasing blood glucose by stimulating hepatic glucose production.

🟢 One detail to remember is that glucagon is secreted by pancreatic alpha cells, not by the liver. The liver is the target organ where glycogen is broken down.

🟢 This makes glucagon the correct answer even though the question wording says “secreted by the liver.”

🟢 It works in opposition to insulin, which lowers blood glucose.

🟢 For exams, think: glucagon = breaks down liver glycogen = raises sugar.

🔹 Cortisol is incorrect because cortisol can increase blood glucose, but it is not the primary hormone that directly triggers glycogenolysis in the way this question is asking.

🔹 Insulin is incorrect because insulin lowers blood glucose by promoting uptake and storage, not release from glycogen.

🔹 Thyroid-stimulating hormone is incorrect because TSH regulates thyroid function, not glycogen breakdown.

🔷 A fasting plasma glucose of 126 mg/dL or higher after at least 8 hours of fasting is diagnostic of diabetes mellitus.

🔷 This client’s result of 130 mg/dL exceeds that threshold and is most indicative of diabetes.

🔷 Fasting glucose reflects baseline glucose regulation and is one of the standard diagnostic criteria.

🔷 Persistent hyperglycemia results from impaired insulin secretion, insulin resistance, or both.

🔷 This makes the fasting glucose value the strongest diagnostic finding among the options.

❌ Hemoglobin A1c of 5.0% is within normal range and does not support diabetes. ❌ Diabetes is generally diagnosed when A1c is 6.5% or higher.

❌ Random plasma glucose of 150 mg/dL is not diagnostic by itself. ❌ A random glucose usually must be 200 mg/dL or greater with symptoms to support diagnosis.

❌ Hemoglobin A1c of 3.0% is abnormally low rather than indicative of diabetes. ❌ This finding may suggest other issues, not chronic hyperglycemia.

💎 Gynecomastia is enlargement of male glandular breast tissue.

💎 It presents as firm tissue located directly beneath the areola, which matches this finding.

💎 It differs from fat accumulation because the tissue is glandular and often rubbery or firm.

💎 Causes can include hormonal changes, medications, liver disease, or endocrine disorders.

💎 The location and tissue description make gynecomastia the best answer.

❌ Axillary lymphatic hypertrophy involves lymph node enlargement in the axilla, not beneath the areola. ❌ It would not present as subareolar glandular tissue.

❌ Soft fatty overgrowth refers to adipose tissue rather than firm glandular tissue. ❌ This describes pseudogynecomastia, not true gynecomastia.

❌ Lipoma is a soft, mobile fatty tumor. ❌ It does not typically present as firm glandular enlargement under the nipple.

🎯 The pituitary gland is known as the master gland because it releases stimulating hormones that regulate other endocrine glands.

🎯 It controls thyroid, adrenal, and gonadal function through trophic hormones.

🎯 Examples include TSH, ACTH, FSH, and LH, which direct target glands to release hormones.

🎯 Although regulated by the hypothalamus, the pituitary directly drives much of endocrine control.

🎯 This central regulatory role is why it is called the master gland.

❌ Hypothalamus helps regulate endocrine function but is not typically called the master gland. ❌ It primarily controls the pituitary.

❌ Thyroid gland regulates metabolism but does not direct multiple endocrine glands. ❌ It is controlled partly by pituitary TSH.

❌ Adrenal gland produces hormones but does not function as the body’s endocrine controller. ❌ It is influenced by pituitary ACTH.

✅ Daily foot inspection helps identify injuries early in clients with diabetes.

✅ Neuropathy can reduce sensation, so clients may not feel wounds or pressure injuries.

✅ Inspecting between the toes helps detect moisture, fungal infection, cracks, or skin breakdown.

✅ Early detection lowers the risk of ulcers, infection, and amputation.

✅ This statement demonstrates correct understanding of diabetic foot care prevention.

❌ Trimming toenails weekly may be unsafe if done improperly. ❌ Clients with neuropathy or poor circulation may need podiatry assistance.

❌ Walking barefoot increases risk for unnoticed injury. ❌ Clients with diabetes should wear protective footwear, even indoors.

❌ Waiting 3 days before calling the provider can delay treatment. ❌ Nonhealing wounds or skin injury should be reported promptly.
