A client with type 1 diabetes mellitus is being taught self-administration of insulin by a nurse. Which of the following instructions should the nurse include?

Correct Answer: D

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same anatomical region. This practice helps reduce the risk of lipodystrophy, a condition characterized by fatty tissue changes due to repeated insulin injections in the same spot. By rotating sites, the client ensures better insulin absorption and prevents localized skin changes. Injecting air into the vial before withdrawing insulin (Choice A) is unnecessary and not recommended. Drawing up short-acting insulin before long-acting insulin (Choice B) is not a standard practice and can lead to errors in dosing. Storing unopened insulin vials in the freezer (Choice C) is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness.

Correct Answer: C

Rationale: The presence of small blood clots in the urine is an expected finding after a TURP due to the surgical manipulation of the prostate bed and the bladder. However, larger clots can indicate excessive bleeding and should be reported promptly. Urine output of 30 mL/hr is within the expected range for post-TURP clients, indicating adequate kidney perfusion. Pink-tinged urine is also normal after a TURP due to minor bleeding from the surgical site. A blood pressure of 114/78 mm Hg is within normal limits and does not require immediate reporting.

Correct Answer: A

Rationale: Facial flushing is a common symptom of early dumping syndrome, which occurs when food moves too quickly into the small intestine. This rapid movement triggers the release of vasoactive peptides causing vasodilation, leading to facial flushing. Syncope (choice B) is not a typical finding in early dumping syndrome. Diaphoresis (choice C) and bradycardia (choice D) are also not characteristic symptoms of early dumping syndrome.

Correct Answer: C

Rationale: The correct answer is C. A serum potassium level of 3.0 mEq/L is below the normal range and indicates hypokalemia, which should be reported to the provider. Hypokalemia can lead to serious complications such as cardiac arrhythmias. Choices A, B, and D are within normal ranges and do not require immediate reporting. A blood glucose level of 150 mg/dL is slightly elevated but not critically high. A serum sodium level of 138 mEq/L is within the normal range. A serum albumin level of 3.8 g/dL is also within the normal range.

Correct Answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

Correct Answer: C

Rationale: In clients with Syndrome of Inappropriate Antidiuretic Hormone (SIADH), the nurse should expect hyponatremia. SIADH leads to excess water retention, diluting the sodium levels in the blood, resulting in low serum sodium levels. Choice A, increased urine output, is incorrect as SIADH causes water retention, leading to decreased urine output. Choice B, increased serum sodium, is incorrect because SIADH causes a dilutional effect due to water retention, resulting in decreased serum sodium levels. Choice D, hypercalcemia, is unrelated to SIADH and not a typical finding.

Correct Answer: D

Rationale: The correct intervention for a client receiving radiation therapy to the head and neck is to avoid exposure to direct sunlight. Direct sunlight should be avoided to protect the skin from further irritation and damage caused by the radiation therapy. Instructing the client to use an alcohol-free mouthwash is important to prevent irritation and maintain oral hygiene, making choice A incorrect. Applying heat packs to the radiation site is contraindicated as heat can further aggravate the skin, making choice B incorrect. Providing a diet low in carbohydrates is not directly related to radiation therapy to the head and neck, so choice C is also incorrect.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a patient with suspected pulmonary embolism. Maintaining adequate oxygenation is crucial in these patients to prevent hypoxemia and support oxygen delivery to tissues. Administering anticoagulants may be necessary but is not the initial priority. Administering bronchodilators is not indicated for pulmonary embolism. Repositioning the patient does not address the immediate need for oxygenation.

Correct Answer: A

Rationale: The correct answer is to check oxygen saturation. This is because checking oxygen saturation provides a direct measure of how well the patient is oxygenating post-surgery. It helps healthcare providers assess if the patient is receiving enough oxygen to meet their body's needs. Auscultating lung sounds (choice B) is important to assess respiratory function but may not provide an immediate indication of oxygenation status. Checking for abnormal breath sounds (choice C) is relevant but does not directly assess oxygenation levels. Checking skin color (choice D) can provide some information about oxygenation, but it is not as precise or direct as measuring oxygen saturation.
