Question 1 of 5
A postpartum client who had an episiotomy expresses concern about the appearance and healing of the incision site. What nursing intervention should be prioritized to promote optimal wound healing?
Correct Answer: C
Rationale: The priority nursing intervention to promote optimal wound healing in a client who had an episiotomy is providing perineal care using peri-bottles with warm water. Warm water helps to cleanse the area, reduce the risk of infection, and promote circulation, which aids in wound healing. Peri-bottles are especially gentle and effective in cleaning the perineal area without causing trauma to the incision site. Encouraging frequent perineal hygiene with soap and water may be too harsh on the incision site and could lead to irritation. Applying antibiotic ointment after each void is not necessary unless prescribed by the healthcare provider, as overuse of antibiotics can lead to resistance. Instructing the client on proper peri-pad application is important for comfort and cleanliness but is not as crucial as gentle perineal care using peri-bottles with warm water for promoting optimal wound healing.
Question 2 of 5
When the patient turned 69 years old, Orinase was discontinued and NPH insulin is prescribed for her. After several months, she is determined to be suffering from sumogyi effect. Which of the following conditons will most likely result when the patient is receiving too much insulin?
Correct Answer: A
Rationale: When a patient is receiving too much insulin, the most likely result is hypoglycemia, not hyperglycemia. The excess insulin causes the blood glucose level to drop too low, leading to symptoms such as sweating, tremors, confusion, and in severe cases, seizures. The body responds to hypoglycemia by releasing counterregulatory hormones such as glucagon, epinephrine, and cortisol, which work to increase the blood glucose level. This rebound effect, known as the Somogyi effect, can result in the patient experiencing high blood glucose levels after a period of insufficient glucose supply due to excessive insulin administration.
Question 3 of 5
Which of the following mechanisms is responsible for the generation of diversity in the antigen-binding sites of immunoglobulins?
Correct Answer: A
Rationale: Somatic hypermutation is the mechanism responsible for generating diversity in the antigen-binding sites of immunoglobulins. During somatic hypermutation, point mutations are introduced into the variable regions of immunoglobulin genes in B cells. These mutations occur randomly and lead to a wide range of amino acid changes in the antigen-binding sites of antibodies. As a result, a diverse repertoire of antibodies with varying specificities for different antigens is created. Gene rearrangement and isotype switching are other mechanisms that contribute to antibody diversity but do not specifically target the antigen-binding sites. Clonal expansion, on the other hand, refers to the proliferation of specific B cell clones after activation by antigens, which amplifies the immune response but does not directly impact the diversity of antigen-binding sites.
Question 4 of 5
A pregnant woman presents with painless, bright red vaginal bleeding at 34 weeks gestation. On examination, the cervix is found to be closed. Which of the following conditions is the most likely cause of these symptoms?
Correct Answer: C
Rationale: Placenta previa is a condition where the placenta partially or completely covers the cervix, leading to painless vaginal bleeding during pregnancy. In the scenario described, the painless, bright red vaginal bleeding at 34 weeks gestation with a closed cervix is classic for placenta previa. This condition is more common in the third trimester and can be diagnosed through ultrasound. It is important to manage placenta previa carefully to prevent complications such as severe bleeding, preterm birth, and maternal/fetal distress.
Question 5 of 5
When a patient is admitted to the OB ward with complains of dizziness and body weakness, this is an example of______.
Correct Answer: D
Rationale: When a patient is admitted to the OB ward with complaints of dizziness and body weakness, this information pertains to what the patient is feeling or experiencing, which is subjective data. Subjective data is based on the patient's symptoms, feelings, and experiences as reported by the patient themselves. In this case, dizziness and body weakness are subjective symptoms described by the patient, and they cannot be objectively measured or quantified. It is essential for healthcare providers to consider subjective data along with objective data (measurable and observable signs) when assessing and diagnosing a patient's condition.
