A patient with chronic obstructive pulmonary disease (COPD) is prescribed albuterol (salbutamol) inhaler as a rescue medication. Which of the following best describes the pharmacological action of albuterol?
- A. Anticholinergic
- B. Beta-adrenergic agonist
- C. Corticosteroid
- D. Methylxanthine
Correct Answer: B
Rationale: Albuterol, also known as salbutamol, is a beta-adrenergic agonist medication commonly used for the treatment of conditions such as asthma and COPD. As a beta-adrenergic agonist, albuterol binds to beta-2 adrenergic receptors in the lungs, causing bronchodilation, which helps to relieve bronchospasms and improve airflow to the lungs. This action leads to the relaxation of smooth muscle in the airways, thus making breathing easier for patients with COPD or asthma. Anticholinergics, corticosteroids, and methylxanthines have different mechanisms of action and are not directly related to the pharmacological action of albuterol in COPD treatment.

What is the first step in the management of a chemical splash to the eyes?
- A. Irrigate the eyes with clean water.
- B. Instill antibiotic eye drops.
- C. Cover both eyes with a sterile dressing.
- D. Assess visual acuity.
Correct Answer: A
Rationale: The first step in the management of a chemical splash to the eyes is to irrigate the eyes with clean water. Flushing the affected eye with water helps to remove the chemical and minimize any potential injury. It is important to continue irrigation for at least 15-20 minutes to ensure thorough removal of the chemical. This prompt action can help prevent further damage to the eye and surrounding tissue. It is crucial to remember not to delay irrigation to seek medical advice first, as immediate irrigation is vital in such situations. After irrigating the eyes, further assessment and treatment can be carried out based on the severity of the injury.
A postpartum client who experienced a vaginal delivery expresses concerns about resuming sexual activity. What information should the nurse provide to address the client's concerns?
- A. Discuss the potential use of barrier contraceptives for contraception.
- B. Educate the client about the normal changes in sexual desire and response.
- C. Recommend delaying sexual activity until the postpartum check-up.
- D. Encourage the client to use lubricants to alleviate discomfort.
Correct Answer: B
Rationale: Option B is the most appropriate response when addressing a postpartum client's concerns about resuming sexual activity after a vaginal delivery. Educating the client about the normal changes in sexual desire and response following childbirth can help alleviate anxiety and provide reassurance. It is crucial for the nurse to explain that it is common for women to experience changes in libido, physical discomfort, and emotional adjustments after giving birth. By discussing these normal postpartum changes, the nurse can support the client in understanding that her feelings are valid and that it may take time for her to feel ready to engage in sexual activity again. Furthermore, the nurse can provide information on ways to enhance comfort and intimacy when resuming sexual activity, such as communication with partners, using lubricants, and gradually easing back into sexual activity as desired.
Patient Josephine asks why her labor is much shorter compared to previous deliveries. Which of the following is the BEST RESPONSE?
- A. Onset of contraction was gradual.
- B. Multigravida patient has shorter labor,
- C. Cervical lengthening was longer.
- D. Induction of labor was done.
Correct Answer: B
Rationale: The statement "Multigravida patient has shorter labor" is the best response to Patient Josephine's question about her shorter labor compared to previous deliveries. In obstetrics, it is commonly observed that labor tends to be shorter in patients who have had previous pregnancies (multigravida patients) due to factors such as prior cervical changes and previous stretching of the birth canal. This phenomenon is known as "multigravida cervical efficiency," and it can lead to faster and more efficient labors in subsequent pregnancies for women who have had previous deliveries.
On the question as to which of the following are the effects of AIDS on pregnancy, one teenager cited a wrong answer which was ________.
- A. Mild weight loss
- B. Repeated abortion
- C. Prematurity
- D. Infertility
Correct Answer: B
Rationale: The effects of AIDS on pregnancy do not generally include repeated abortion as a direct consequence. AIDS can impact pregnancy by increasing the risk of complications such as premature birth, low birth weight, and potential transmission of the virus from mother to child. Infertility can also be a concern, but repeated abortion is not a common effect of AIDS on pregnancy. It is important to provide accurate information about the effects of AIDS on pregnancy to ensure proper understanding and support for individuals affected by this condition.
A postpartum client reports severe perineal pain and difficulty passing stools following a vaginal delivery. Which nursing intervention should be implemented?
- A. Administering a stool softener as ordered
- B. Encouraging the client to refrain from defecation until pain subsides
- C. Applying ice packs to the perineum for pain relief
- D. Providing education on proper perineal hygiene
Correct Answer: A
Rationale: Administering a stool softener as ordered is the most appropriate nursing intervention for a postpartum client experiencing severe perineal pain and difficulty passing stools following a vaginal delivery. Stool softeners help to soften the stool, making it easier for the client to pass without straining, which can exacerbate perineal pain. It is important to follow the healthcare provider's orders when administering medications to ensure proper dosing and effectiveness. Encouraging the client to refrain from defecation may lead to constipation and worsen the situation. Applying ice packs to the perineum can provide temporary pain relief, but addressing the underlying issue of constipation with a stool softener is more effective in the long term. Providing education on proper perineal hygiene is important for overall postpartum care, but addressing the immediate issue of constipation with a stool softener takes precedence in this scenario.
