Through which of the following does lymph return to the blood?
- A. Carotid arteries
- B. Inferior vena cava
- C. Aorta
- D. Subclavian veins
Correct Answer: D
Rationale: The correct answer is D: Subclavian veins. Lymph returns to the blood through the subclavian veins because they receive lymphatic drainage from the thoracic duct and right lymphatic duct. Lymphatic vessels merge into lymphatic ducts, which empty into the subclavian veins, allowing lymph to re-enter the bloodstream. The carotid arteries (A) carry oxygen-rich blood to the brain, the aorta (C) is the main artery of the body carrying oxygenated blood from the heart, and the inferior vena cava (B) returns deoxygenated blood from the lower body to the heart. Therefore, choices A, B, and C are incorrect as they are not involved in the return of lymph to the blood.

In addition to antibiotics, which of the ff. recommendations can the nurse make to increase comfort in a patient experiencing sinusitis? Choose all answers that are correct. i. Coughing and deep breathing iv. Room humidifier ii. Sinus irrigation v. Percussion and postural drainage iii. Hot moist packs vi. Semi-fowler’s position
- A. 1 ,2 and 5
- B. 1, 3, 4 and 5
- C. 3, 4 and 6
- D. 2, 4, 5 and 6
Correct Answer: D
Rationale: The correct answer is D: 2, 4, 5, and 6.
1. Room humidifier (choice 2) helps to keep the air moist, which can ease sinus pressure and discomfort.
2. Hot moist packs (choice 4) can provide relief by reducing congestion and promoting sinus drainage.
3. Percussion and postural drainage (choice 5) can help loosen mucus and improve drainage.
4. Semi-fowler's position (choice 6) can also aid in drainage and reduce sinus pressure.
Choices A, B, and C are incorrect because they do not include all the recommended interventions that can help increase comfort in a patient with sinusitis. Each of the incorrect choices is missing at least one crucial recommendation that is beneficial for managing sinusitis symptoms.
An oncology nurse educator is speaking to a women’s group about breast cancer. Questions and comments from the audience reveal a misunderstanding of some aspects of the disease. Various members of the audience have made all of the following statements. Which one is accurate?
- A. Mammography is the most reliable method for detecting breast cancer.
- B. Breast cancer is the leading killer of women of childbearing age.
- C. Breast cancer requires a mastectomy.
- D. Men can develop breast cancer.
Correct Answer: D
Rationale: The correct answer is D: Men can develop breast cancer. This is accurate because although breast cancer is more common in women, men can also develop the disease due to the presence of breast tissue in their bodies. This is a crucial point to emphasize to raise awareness about breast cancer among men.
Incorrect choices:
A: Mammography is not the most reliable method for detecting breast cancer, as it may not detect all types of breast cancer.
B: Breast cancer is not the leading killer of women of childbearing age, as there are other leading causes of death in this age group.
C: Breast cancer does not always require a mastectomy; treatment options vary depending on the individual case.
Summary: Choice D is correct as it highlights the important fact that men can also develop breast cancer, which is often overlooked. Choices A, B, and C are incorrect due to inaccuracies or oversimplifications of the facts related to breast cancer detection, statistics, and treatment.
The nurse is aware that multiple sclerosis is a progressive disease of the central nervous system characterized by:
- A. Axon degeneration
- B. Sclerosed patches of nervous system
- C. Demyelination of the brain and spinal cord
- D. All of the above
Correct Answer: D
Rationale: Step 1: Multiple sclerosis (MS) is a progressive disease affecting the central nervous system.
Step 2: Axon degeneration occurs in MS, leading to impaired nerve signal transmission.
Step 3: MS is characterized by sclerosed patches, or plaques, in the nervous system.
Step 4: Demyelination of the brain and spinal cord is a hallmark feature of MS.
Step 5: Therefore, all of the above choices are correct as they accurately describe key features of MS.
What should a male client over age 50 do to help ensure early identification of prostate cancer?
- A. Have a digital rectal examination and prostate-specific antigen (PSA) test done yearly
- B. Have a transrectal ultrasound every 5 years
- C. Perform monthly testicular self-examinations, especially after age 50
- D. Have a complete blood count (CBC) and blood urea nitrogen (BUN) and creatinine levels
Correct Answer: A
Rationale: Rationale:
1. Digital rectal exam (DRE) and PSA test are recommended by major health organizations for prostate cancer screening in men over 50.
2. DRE helps detect abnormalities in the prostate, while PSA test measures the levels of a protein produced by the prostate gland.
3. Prostate cancer can be asymptomatic in its early stages, so regular screening is crucial for early detection and treatment.
4. Transrectal ultrasound is not a primary screening method for prostate cancer.
5. Testicular self-exams are for detecting testicular cancer, not prostate cancer.
6. CBC, BUN, and creatinine levels are not specific tests for prostate cancer screening.
What is the purpose of pursed lip breathing?
- A. Helps exhale less volume of air during expiration
- B. Increases expiration
- C. Promotes effective use of the diaphragm
- D. Relieves compensatory burden on upper thorax
Correct Answer: A
Rationale: The correct answer is A because pursed lip breathing helps to slow down and control the exhalation process, allowing the individual to exhale a smaller volume of air with more force. This helps to prevent air trapping in the lungs, improve oxygen exchange, and reduce shortness of breath.
B: Incorrect - Pursed lip breathing does not increase expiration but rather controls it.
C: Incorrect - While pursed lip breathing can promote deep breathing and better oxygen exchange, its primary purpose is to regulate exhalation volume.
D: Incorrect - Pursed lip breathing does not specifically target the upper thorax but rather facilitates a more efficient breathing pattern by reducing air trapping in the lungs.
