Which of the following explanations by the nurse will help a patient understand what to expect during a bronchoscopy?

Correct Answer: A

Rationale: The correct answer is A because it accurately describes the procedure of bronchoscopy. The nurse's explanation should focus on the insertion of a small tube through the nose or mouth into the bronchi to visualize the airways. This information helps the patient understand the basic process and what to expect during the procedure. Choice B is incorrect as bronchoscopy does not involve breathing a radioactive substance to show diseased areas in the lungs. Choice C is also incorrect as there is no requirement to drink a thick white liquid for bronchoscopy. Choice D is incorrect as dye injection is not a standard part of bronchoscopy, and asking about allergies to dye is irrelevant in this context.

Correct Answer: A

Rationale: The correct answer is A because successful treatment of diabetes insipidus aims to reduce excessive urine output and dehydration. A fluid intake of less than 2,500mL in 24 hours indicates proper control of fluid balance. Choice B is incorrect because urine output of more than 200mL/hour suggests ongoing excessive fluid loss, which is not indicative of successful treatment. Choice C is incorrect as a blood pressure of 90/50mmHg is low and may indicate hypotension, which is not a specific indicator of successful diabetes insipidus treatment. Choice D is incorrect because a pulse rate of 126 beats/min is not a direct marker of diabetes insipidus treatment success. In summary, the correct indicator of successful treatment of diabetes insipidus is a reduction in fluid intake, option A, as it signifies improved fluid balance and hydration status.

Correct Answer: A

Rationale: The correct answer is A because reassessing the client's diet, medication, and lifestyle habits allows the nurse to identify any factors contributing to the elevated blood glucose levels. By identifying possible issues, the nurse can make necessary adjustments to the treatment plan to better manage the client's condition. Increasing medication dosage without understanding the root cause may lead to adverse effects. Simply documenting the elevated levels without taking proactive measures does not address the problem. Notifying the client's family is not the nurse's first action; the focus should be on assessing and addressing the client's needs.

Correct Answer: A

Rationale: The correct answer is A, the 50-year-old with an ileostomy, should be monitored most closely for dehydration. Patients with an ileostomy have a higher risk of dehydration due to increased fluid loss through the stoma. Monitoring their fluid intake, output, electrolyte levels, and signs of dehydration is crucial to prevent complications. The other choices are less likely to experience severe dehydration compared to the patient with an ileostomy. The 72-year-old with diabetes mellitus may be at risk for dehydration, but it is not as high a risk as the patient with an ileostomy. The 19-year-old with chronic asthma and the 28-year-old with a broken femur are not as directly related to dehydration compared to the patient with an ileostomy.

Correct Answer: C

Rationale: Correct Answer: C - Diffusion Rationale: Diffusion is the movement of a substance from an area of higher concentration to an area of lower concentration. This process occurs naturally to achieve equilibrium. In the context of fluids and electrolytes, this movement helps maintain balance within the body. Unlike osmosis, which involves the movement of water molecules across a semi-permeable membrane, diffusion applies to the movement of all types of substances. Filtration involves the movement of substances through a barrier under pressure, and active transport requires energy to move substances against a concentration gradient. Therefore, the correct answer is diffusion as it aligns with the principle of movement from high to low concentration for achieving equilibrium.

Correct Answer: A

Rationale: The correct answer is A: Prevent clot formation. Heparin is an anticoagulant that inhibits the formation of blood clots. In DIC (Disseminated Intravascular Coagulation), there is excessive clotting throughout the body, leading to organ damage. By administering heparin, we aim to prevent further clot formation and reduce the risk of complications. Choice B is incorrect because heparin does not increase clot formation; it works to inhibit clotting. Choice C is incorrect as heparin does not directly increase blood flow to target organs. Choice D is also incorrect as heparin does not decrease blood flow to target organs; its primary role is anticoagulation.

Correct Answer: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.

Correct Answer: C

Rationale: The correct answer is C. Washing feet in hot water is not part of diabetic foot care as it can lead to burns or skin damage. A: Properly fitting shoes help prevent injuries. B: Trimming toenails straight reduces risk of ingrown nails. D: Wearing shoes on hot surfaces protects feet from burns or injuries. Overall, C is incorrect due to its potential harm to the client's feet.

Correct Answer: B

Rationale: The correct answer is B: Bence jones protein in the urine. In multiple myeloma, abnormal plasma cells produce excess monoclonal immunoglobulins, including Bence Jones proteins, which can be detected in the urine. This is a hallmark finding in multiple myeloma diagnosis. A: Incorrect. Serum creatinine levels are typically not affected in multiple myeloma. C: Incorrect. Hypercalcemia, not hypocalcemia, is commonly seen in multiple myeloma due to bone destruction. D: Incorrect. Multiple myeloma often presents with high serum protein levels, not low levels.
