1. What type of immunity do vaccines provide?
- A. active
- B. passive
- C. transplacental
- D. active and passive
Correct answer: A
Rationale: Vaccines provide active immunity by stimulating the immune system to produce antibodies against specific pathogens. Choice B, passive immunity, is acquired from ready-made antibodies, not through vaccination. Choice C, transplacental immunity, is a form of passive immunity transferred from mother to infant, not acquired through vaccines. Therefore, the correct answer is active immunity.
2. A woman in labor whose cervix is not completely dilated is pushing strenuously during contractions. Which method of breathing should the nurse encourage the woman to perform to help her overcome the urge to push?
- A. Holding her breath and using the Valsalva maneuver
- B. Blowing repeatedly in short puffs
- C. Cleansing breaths
- D. Deep inspiration and expiration at the beginning and end, respectively, of each contraction
Correct answer: B
Rationale: If a woman pushes strenuously before the cervix is completely dilated, she risks injury to the cervix and the fetal head. Blowing prevents closure of the glottis and breath-holding, helping overcome the urge to push strenuously. The woman would be encouraged to blow repeatedly, using short puffs, when the urge to push is strong. This breathing technique allows for controlled exhalation and helps prevent unnecessary pushing. Cleansing breaths (deep inspiration and expiration at the beginning and end of each contraction) are encouraged during the first stage of labor to provide oxygenation and reduce myometrial hypoxia and to promote relaxation. Holding her breath and using the Valsalva maneuver (choice A) is not recommended as it can increase intra-abdominal pressure and decrease venous return, potentially compromising fetal oxygenation. Deep inspiration and expiration at the beginning and end of each contraction (choice D) are more suitable for relaxation and oxygenation purposes rather than managing the urge to push.
3. A 65-year-old female client is experiencing postmenopausal bleeding. Which type of physician should this client be encouraged to see?
- A. a radiologist
- B. a gynecologist
- C. a physiatrist
- D. an oncologist
Correct answer: B
Rationale: A 65-year-old female experiencing postmenopausal bleeding should be encouraged to see a gynecologist. Gynecologists specialize in treating and managing diseases of the female reproductive organs, making them the most appropriate physician for this issue. Postmenopausal bleeding can indicate various gynecological conditions such as endometrial atrophy, endometrial hyperplasia, or endometrial cancer, highlighting the importance of consulting a gynecologist for proper diagnosis and management. Radiologists evaluate X-rays, physiatrists manage rehabilitation teams, and oncologists treat clients with cancer. Therefore, in this case, the symptoms point towards a gynecological problem, emphasizing the necessity of seeking care from a gynecologist.
4. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?
- A. Assessing visual acuity
- B. Inspecting the eyelids for ptosis
- C. Assessing pupil constriction
- D. Assessing ocular movements
Correct answer: A
Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.
5. What effect can medication bound to protein have?
- A. reduced drug availability
- B. limited distribution of the drug to receptor sites
- C. less availability to produce desired medicinal effects
- D. decreased metabolism of the drug by the liver
Correct answer: C
Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.
