A patient presents to the emergency department following a motor vehicle crash and suffers a right femur fracture. The leg is stabilized in a full leg cast. Otherwise, the patient has no other major injuries, is in good health, and reports only moderate discomfort. Which is the most pertinent nursing diagnosis the nurse will include in the plan of care?

Correct Answer: C

Rationale: The most pertinent nursing diagnosis for the patient with a right femur fracture stabilized in a full leg cast is "Acute pain" (Choice C). The rationale for this is as follows: 1. The patient is experiencing moderate discomfort due to the fracture and immobilization in the cast, indicating a need for pain management. 2. Acute pain is a priority in this situation as it can impact the patient's comfort, mobility, and overall recovery. 3. Managing pain effectively is crucial for promoting healing, preventing complications, and improving the patient's quality of life. 4. Posttrauma syndrome (Choice A) may be a consideration in the long term but is not the immediate priority. Constipation (Choice B) is not the most pertinent nursing diagnosis in this scenario. Anxiety (Choice D) may be present but addressing pain is more urgent and directly related to the patient's current condition.

Correct Answer: A

Rationale: The correct answer is A: Oxygen. Oxygen is primarily transported in the blood bound to hemoglobin within red blood cells, not dissolved in plasma. Carbon dioxide is transported in plasma. Nutrients and hormones are also transported in plasma. Therefore, choice A is incorrect as oxygen is not primarily transported in plasma.

Correct Answer: C

Rationale: The correct answer is C. Rolling Mr. Gabatan on his abdomen, placing a pad under his head, and covering him with any material available is the appropriate action. This position helps protect his airway and prevents potential complications from a possible spinal injury. It also allows for better assessment of his condition by healthcare professionals. Choice A is incorrect because leaving Mr. Gabatan on his back and instructing him to move can worsen any spinal injury he may have sustained. Choice B is incorrect because raising him to a sitting position can also exacerbate his condition. Choice D is incorrect because moving him without proper stabilization can lead to further injury.

Correct Answer: D

Rationale: The correct answer is D: Loss of peripheral vision. Macular degeneration affects the central vision, specifically the macula, which is responsible for central vision and sharp detail. Loss of peripheral vision is not a typical symptom of macular degeneration. The macula is located in the center of the retina, so symptoms would relate to central vision impairments such as decreased ability to distinguish colors, loss of central vision, and loss of near vision. Peripheral vision is not primarily affected by macular degeneration, hence it is not an expected symptom.

Correct Answer: D

Rationale: The correct answer is D: Polyps. Polyps in the colon are precancerous growths that can develop into colorectal cancer over time. Identifying polyps during a medical history interview can raise suspicion for colorectal cancer due to their potential to progress into malignancy. Duodenal ulcer (A) is not directly related to colorectal cancer. Weight gain (B) is a non-specific symptom and does not specifically indicate colorectal cancer. Hemorrhoids (C) are common and usually benign, not directly linked to colorectal cancer.

Correct Answer: D

Rationale: The correct answer is D, assess vital signs, as it is crucial to monitor the client's hemodynamic stability and response to treatment during the critical initial 24 hours of Addisonian crisis. Vital signs such as blood pressure, heart rate, and respiratory rate provide valuable information about the client's condition and response to therapy. Weighing the client (choice A) and testing urine for ketones (choice C) may be important but not as immediately critical as monitoring vital signs. Administering oral hydrocortisone (choice B) is essential for treatment but does not require frequent administration within the first 24 hours.

Correct Answer: B

Rationale: The correct answer is B. Monitoring for signs of restlessness, sweating, and excessive weight loss during thyroid replacement therapy is essential in managing hyperthyroidism. Restlessness can indicate increased metabolic rate, sweating can be due to excessive heat production, and weight loss can be a sign of overactive thyroid function. Providing extra blankets (Choice A) may worsen symptoms of heat intolerance. Balancing activity and rest (Choice C) is important, but not specific to hyperthyroidism. Encouraging activity to prevent constipation (Choice D) is not directly related to managing hyperthyroidism.

Correct Answer: D

Rationale: The correct answer is D: Hypocalcemia. Severe diarrhea can lead to electrolyte imbalances, including low calcium levels. Decreased muscle tone and deep tendon reflexes are classic signs of hypocalcemia. Calcium is essential for proper muscle function and nerve transmission. Hypernatremia (A) is high sodium levels, not related to decreased muscle tone. Hyperchloremia (B) is high chloride levels, not associated with muscle tone changes. Hypokalemia (C) is low potassium levels, which can cause muscle weakness but not specifically decreased muscle tone and deep tendon reflexes like hypocalcemia.

Correct Answer: C

Rationale: Rationale: Choice C is the correct answer because drinking lots of water at night actually helps prevent UTIs by flushing out bacteria from the urinary tract. Holding the urge to urinate (Choice A) can increase the risk of UTIs as bacteria can multiply in stagnant urine. Insertion of instruments and catheters (Choice B) can introduce bacteria, leading to infection. Unhygienic cleaning after defecation (Choice D) can also introduce bacteria to the urinary tract, causing UTIs. Therefore, Choice C is the exception as it does not contribute to the common causes of UTIs.
