The nurse is preparing to insert a nasogastric tube in a patient who is semiconscious. To determine the length of the tube needed to be inserted, how should the nurse measure the tube?

Correct Answer: C

Rationale: Rationale for Correct Answer (C): To determine the correct length of the nasogastric tube needed to be inserted, the nurse should measure from the tip of the earlobe to the nose and then to the xiphoid process. This method ensures that the tube reaches the stomach without coiling in the esophagus or being inserted too far down. The distance from the earlobe to the nose approximates the distance from the nose to the stomach, and measuring to the xiphoid process ensures proper placement. This technique minimizes the risk of complications such as aspiration or misplacement. Summary of Incorrect Choices: A: Measuring from the tip of the nose to the earlobe is incorrect because it does not take into account the distance to the stomach. B: Measuring from the tip of the earlobe to the xiphoid process alone is incorrect because it does not consider the distance through the nasal passage. D: Measuring from the tip of the nose to the earlobe to

Correct Answer: C

Rationale: The correct answer is C: bacterial endocarditis. Mitral valve stenosis increases the risk of bacterial endocarditis due to turbulent blood flow and potential damage to the heart valve. Prophylactic antibiotics are recommended before certain procedures to prevent bacterial endocarditis in patients with underlying cardiac conditions. Choice A, hypertension, is incorrect as mitral valve stenosis does not directly increase the risk of developing hypertension. Choice B, postpartum infection, is not directly related to the risk associated with mitral valve stenosis. Choice D, upper respiratory infections, is not a specific risk associated with mitral valve stenosis in pregnant patients.

Correct Answer: A

Rationale: The correct answer is A because hemorrhage is the primary concern in ectopic pregnancy due to the risk of rupture and severe bleeding. Immediate intervention is crucial to prevent life-threatening complications. Choice B is incorrect as future fertility may be affected but is not the immediate concern. Choice C is incorrect as bed rest and analgesics are not effective treatments for ectopic pregnancy. Choice D is incorrect as a D&C is not performed in ectopic pregnancy; surgical intervention is required to remove the ectopic pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Decreased skin turgor. Diarrhea leads to fluid loss, causing dehydration and decreased skin turgor. This indicates the patient's hydration status. A: Distended abdomen is more common in conditions like bowel obstruction, not necessarily in diarrhea. C: Increased energy levels are unlikely due to the patient's weakened state from dehydration. D: Elevated blood pressure is not typically associated with dehydration.

Correct Answer: A

Rationale: The correct answer is A: The patient can be anxious, making it difficult for abdominal and perineal muscles to relax enough to void. Rationale: Anxiety can lead to tension in the abdominal and perineal muscles, inhibiting the ability to relax and urinate. The sympathetic nervous system response to anxiety can cause urinary retention. So, the patient's frustration in voiding in front of the nurse may be due to anxiety hindering muscle relaxation. Summary of other choices: B: The patient not recognizing physiological signals is less likely as the patient requested assistance to void, indicating awareness of the need to urinate. C: The patient being lonely and seeking attention is not relevant to the inability to void in front of the nurse. D: Inadequate fluid intake may contribute to decreased urine output but is not directly related to the inability to void in front of the nurse.

Correct Answer: B

Rationale: The correct answer is B because assessing and promoting the patient's coping skills is essential in addressing the psychosocial needs of a patient with macular degeneration. By understanding how the patient is coping with the vision loss, the nurse can tailor interventions to support the patient effectively. This approach acknowledges the patient's emotional responses and helps them navigate the challenges associated with the condition. Choice A is incorrect as solely focusing on other senses may not address the psychological impact of vision loss. Choice C is incorrect as it dismisses the significant lifestyle changes the patient may experience. Choice D is incorrect as promoting hope for recovery may not be realistic in the case of irreversible conditions like macular degeneration.

Correct Answer: A

Rationale: The correct answer is A: Lumpectomy and radiation. For a small, well-defined nodule in the breast, lumpectomy (removal of the lump) followed by radiation therapy is usually the treatment of choice for early-stage breast cancer. This approach aims to preserve the breast while ensuring effective treatment. Partial mastectomy (B) involves removing a larger portion of the breast tissue and is not typically necessary for a small, well-defined nodule. Chemotherapy (C) is generally used for more advanced stages of breast cancer or when the cancer has spread beyond the breast. Total mastectomy (D) is considered when the cancer is more extensive or in cases where lumpectomy is not feasible.

Correct Answer: D

Rationale: The correct answer is D: Obese. This classification is based on the Body Mass Index (BMI) calculation, which takes into account weight and height. A BMI above 30 is considered obese, indicating excess body fat. Other choices are incorrect because they do not align with the BMI criteria for obesity. Choice A is incorrect as normal weight falls within a specific BMI range. Choice B is incorrect for individuals with a BMI below the normal range. Choice C is incorrect for individuals with a BMI between the overweight and obese categories.

Correct Answer: C

Rationale: Step 1: The nurse should inform the patient that most cases of ovarian cancer are considered to be random, with no obvious causation. This is the correct answer because the exact cause of ovarian cancer is not well understood, and the majority of cases are not linked to specific risk factors. Step 2: Choice A is incorrect because the use of oral contraceptives actually decreases the risk of ovarian cancer. Step 3: Choice B is incorrect because tobacco use is not a major risk factor for ovarian cancer. It is primarily associated with lung and other types of cancer. Step 4: Choice D is incorrect because while a family history of ovarian cancer can increase the risk, the majority of women diagnosed with ovarian cancer do not have a family history of the disease.
