Which of the following is usually the first symptom of a cataract that the nurse would expect a patient to report during assessment?

Correct Answer: B

Rationale: The correct answer is B: Blurring of vision. This is typically the first symptom of a cataract because the clouding of the lens causes light to scatter, leading to blurred vision. Dry eyes (A) and eye pain (C) are not typically associated with cataracts. Loss of peripheral vision (D) is more commonly seen in conditions like glaucoma. In summary, blurring of vision is the hallmark symptom of cataracts due to lens clouding, distinguishing it from other eye conditions.

Correct Answer: C

Rationale: The correct answer is C: Ask the patient about the facial grimacing with movement. This is the initial action because the discrepancy between the patient's verbal pain level and non-verbal cues needs clarification. By directly asking the patient about the facial grimacing, the nurse can gather more information to assess the actual pain level accurately. This step ensures a comprehensive understanding of the patient's pain experience and guides further interventions. Incorrect choices: A: Proceed to the next patient’s room to make rounds - This choice neglects the need to address the discrepancy in the patient's pain assessment. B: Determine the patient does not want any pain medicine - Assuming the patient's preference without further assessment can lead to inadequate pain management. D: Administer the pain medication ordered for moderate to severe pain - Without clarifying the reason behind the facial grimacing, administering pain medication may not be appropriate and could result in unnecessary medication use.

Correct Answer: B

Rationale: The correct answer is B: Use a low-pitched voice. This is because elderly individuals may have age-related hearing loss, making it difficult for them to hear higher frequencies. Using a low-pitched voice can help ensure that the client can hear and understand the nurse clearly. A: Leaning and shouting at the ear of the client may come across as aggressive and disrespectful. C: Opening the mouth wide while talking is not necessary and may be seen as patronizing. D: Using a medium-pitched voice may still be too difficult for the elderly client to hear clearly due to age-related hearing loss.

Correct Answer: C

Rationale: Step 1: The nurse should explain that bladder irrigation is necessary to prevent blood clots from occluding the catheter after a TURP procedure. Step 2: Without irrigation, blood clots could block the catheter, leading to urinary retention and potential complications. Step 3: This explanation addresses the patient's concern about increased pain and highlights the importance of the irrigation in maintaining proper urine flow. Step 4: Choice A is incorrect because the primary purpose of irrigation is not to stop bleeding but to prevent clot formation. Choice B is incorrect because the irrigation is not for administering antibiotics. Choice D is incorrect as it does not address the issue of clot formation.

Correct Answer: A

Rationale: The correct answer is A because after a total thyroidectomy, the client will no longer produce thyroid hormones, necessitating lifelong replacement therapy. This statement shows an understanding of the need for ongoing medication to maintain thyroid function. Choice B is incorrect as the client had a total thyroidectomy, so there is no risk of hyperthyroidism recurrence. Choice C is incorrect as the client will need ongoing care and monitoring for thyroid function. Choice D is incorrect as increasing caloric intake is not a necessary long-term care measure after a thyroidectomy.

Correct Answer: A

Rationale: The correct answer is A because exercising the bitten extremity can increase the spread of the venom. Choice B is correct as poisonous snake bites typically leave two fang marks. Choice C is correct as immediate severe pain and swelling are common symptoms of a poisonous snake bite. Choice D is incorrect as a tourniquet should not be used for snake bites as it can lead to complications such as tissue damage and increased risk of infection.

Correct Answer: A

Rationale: The correct answer is A: 11mEq/L. In renal failure, the kidneys are unable to excrete excess magnesium, leading to hypermagnesemia. The patient's symptoms of stomach distress and ingesting antacids suggest magnesium intake. A Mg level of 11mEq/L aligns with symptoms like flushed face and weakness. Choices B, C, and D are too low for hypermagnesemia symptoms and would not explain the patient's presentation.

Correct Answer: D

Rationale: The correct answer is D because a brain abscess can be caused by direct invasion of the brain, spread of infection by other organs, and spread of infection from nearby sites. Direct invasion can occur from trauma or surgery, while infections from other organs like the lungs or heart can travel through the bloodstream to the brain. Infections from nearby sites such as the sinuses or ears can also spread to the brain. Therefore, all of these mechanisms can lead to the formation of a brain abscess. Choices A, B, and C alone do not encompass all the possible causes of a brain abscess, making D the correct comprehensive answer.

Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.
