Choose from the following the primary goals of TPN? I. promote weight gain II. improve nutritional status III. maintain muscle mass IV. establish nitrogen balance! V. enhance healing process

Correct Answer: C

Rationale: Total Parenteral Nutrition (TPN) is a method of providing nutrition to patients who cannot or should not obtain their nutrition through regular oral intake. The primary goals of TPN include promoting weight gain, improving nutritional status, maintaining muscle mass, and establishing nitrogen balance. These goals are crucial to support the overall health and well-being of the patient receiving TPN. Enhancing the healing process is an important aspect of TPN as well, but it is not considered one of the primary goals as weight gain, nutritional status, muscle mass, and nitrogen balance are typically the immediate priorities when administering TPN.

Correct Answer: C

Rationale: Rabies has a shorter incubation period if the bite is located on the hand. This is because bites on the hand are more likely to have direct access to nerve pathways, which can lead to a faster spread of the rabies virus to the central nervous system. In general, bites on parts of the body closer to the brain and spinal cord, such as the hand and face, can result in a quicker onset of rabies symptoms compared to bites on farther extremities like the leg or abdomen.

Correct Answer: C

Rationale: Globulin is the blood protein involved in the immune system. There are different types of globulins, including immunoglobulins (antibodies) that play a crucial role in the body's defense against infections. These antibodies bind to foreign substances, such as bacteria and viruses, helping the immune system to recognize and destroy them. Thrombin is a clotting protein, albumin is a protein responsible for maintaining osmotic balance in the blood, and hemoglobin is a protein found in red blood cells that carries oxygen.

Correct Answer: B

Rationale: Adenomyosis is a condition characterized by the presence of endometrial tissue within the myometrium (muscle wall) of the uterus. It can present with symptoms such as cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. On pelvic examination, the uterus may be retroverted (tilted backward) and enlarged due to the presence of adenomyotic nodules within the uterine muscle. Adenomyosis can also cause heavy menstrual bleeding (menorrhagia). Endometriosis, on the other hand, involves the presence of endometrial tissue outside the uterus and can cause similar symptoms but is less likely to result in uterine enlargement or retroversion. Leiomyomas (uterine fibroids) are benign tumors of the uterine muscle and can also cause pelvic pain and abnormal uterine enlargement but are less likely to be associated with dysmenorrhea and infertility

Correct Answer: C

Rationale: A simple hysterectomy involves the removal of the uterus and cervix. It does not involve the removal of the fallopian tubes or ovaries. In some cases, the fallopian tubes may be removed along with the uterus, but this would be specified as a different type of hysterectomy (such as a total hysterectomy or a radical hysterectomy). The removal of the ovaries, if necessary, would be indicated as an oophorectomy.

Correct Answer: D

Rationale: Before initiating any oxygen therapy, it is crucial for the nurse to first assess the patient's condition. This step allows the nurse to determine the patient's oxygen saturation levels, respiratory rate, lung sounds, and overall respiratory status. Understanding the patient's baseline condition helps in selecting the appropriate oxygen delivery method and flow rate that will best meet the patient's needs. Additionally, assessing the patient's condition allows the nurse to monitor the effectiveness of the oxygen therapy and make any necessary adjustments throughout the treatment process. Therefore, assessing the patient's condition is the necessary first step in providing safe and effective oxygen therapy.

Correct Answer: B

Rationale: Validity refers to the extent to which a test accurately measures what it is intended to measure. In the context of screening tests for diseases, validity is crucial in assessing whether the test can correctly distinguish between individuals who have the disease (true positives) and those who do not have the disease (true negatives). This includes the ability to minimize false positives (incorrectly identifying someone as having the disease) and false negatives (incorrectly identifying someone as not having the disease). Therefore, when assessing the ability of a screening test to distinguish correctly between persons with and without a disease, we are essentially evaluating its validity.

Correct Answer: A

Rationale: The development of autoantibodies such as antinuclear antibodies (ANA) and anti-double-stranded DNA (anti-dsDNA) antibodies in systemic lupus erythematosus (SLE) is primarily attributed to a loss of self-tolerance. Self-tolerance refers to the immune system's ability to recognize and differentiate self-antigens from foreign antigens. In individuals with SLE, there is a breakdown in immune tolerance mechanisms, leading to the production of autoantibodies against self-antigens like nuclear components (e.g., DNA, RNA, histones). This loss of self-tolerance results in the immune system targeting and attacking its tissues, leading to the systemic inflammation and tissue damage characteristic of SLE. The presence of elevated levels of ANA and anti-dsDNA antibodies in this patient suggests an autoimmune response against nuclear material, further supporting the role of self-tolerance breakdown in SLE

Correct Answer: D

Rationale: Quantitative research is the type of research that involves collecting numerical data, which can be easily quantified and analyzed statistically. It is characterized by its structured methodology, objectivity, and the ability to control variables to a considerable extent. In the context of a study on sleep, where data related to sleep patterns, duration, quality, etc., need to be measured and analyzed in a systematic manner, quantitative research would be the most appropriate choice. This type of research allows for a more precise understanding of the relationships and patterns within the data, providing valuable insights into the sleep-related factors being studied.
