Recording the strength of muscle contraction as a result of electrical stimulation is known as _________.
- A. Electromyograph
- B. Electroencephalography
- C. Electromyography
- D. Electroencephalography
Correct Answer: C
Rationale: Rationale for Correct Answer (C):
1. Electromyography (EMG) specifically measures muscle contraction strength.
2. It involves placing electrodes on the skin to record electrical activity produced by muscles.
3. EMG is commonly used in clinical and research settings to assess muscle function and diagnose neuromuscular disorders.
Summary of Incorrect Choices:
A. Electromyograph: Incorrect term, should be "Electromyography".
B. Electroencephalography: Measures brain activity, not muscle contraction.
D. Electroencephalography: Same as choice B, measures brain activity, not muscle contraction.

At the time of ovulation, each secondary oocyte is surrounded by a single layer of cells known as a(n) ________.
- A. vesicular (Graafian) follicle
- B. primary follicle
- C. primordial follicle
- D. uterine (fallopian) follicle
Correct Answer: A
Rationale: The correct answer is A: vesicular (Graafian) follicle. At the time of ovulation, the secondary oocyte is surrounded by this structure, which is a mature follicle containing a fluid-filled antrum. This structure is essential for the release of the oocyte during ovulation. The other choices, B: primary follicle, C: primordial follicle, and D: uterine (fallopian) follicle, are incorrect because primary follicles are immature, primordial follicles are the earliest stage of follicle development, and uterine (fallopian) follicle is not a correct anatomical term.
Medial lower arm bone is
- A. Humerus
- B. Radius
- C. Ulna
- D. Carpals
Correct Answer: C
Rationale: The correct answer is C: Ulna. The ulna is the medial lower arm bone located on the pinky side. It articulates with the humerus at the elbow joint and with the radius at the wrist joint. The humerus (A) is the upper arm bone, not located in the lower arm. The radius (B) is the lateral lower arm bone, not the medial one. Carpals (D) refer to the wrist bones, not the lower arm bones. Therefore, the ulna is the correct answer as it is the specific bone that fits the description of being the medial lower arm bone.
Which of the following components of the fetoplacental (endocrine) unit is similar to thyroid stimulating hormone (TSH) and stimulates T4 secretion by the maternal thyroid?
- A. Human chorionic gonadotropin (hCG)
- B. Human chorionic somatomammotropin (hCS, hPL)
- C. IGF I and IGF II
- D. Endothelial growth factor (EGF)
Correct Answer: A
Rationale: Rationale:
1. Human chorionic gonadotropin (hCG) acts like TSH, stimulating T4 secretion by the maternal thyroid.
2. hCG is produced by the placenta and has a similar structure and function to TSH.
3. hCG binds to the TSH receptor on the thyroid gland, triggering T4 release.
4. Other options do not specifically target the thyroid gland for T4 secretion.
Summary:
A: hCG mimics TSH and directly stimulates T4 release.
B: hCS, hPL - involved in placental growth and lactation, not thyroid stimulation.
C: IGF I and II - growth factors, not directly related to thyroid function.
D: EGF - promotes cell growth and differentiation, not linked to thyroid hormone secretion.
You obtain all of these assessment data about your client with continuous bladder irrigation (CBI) after a transurethral resection of the prostate (TURP). Which information indicates the most immediate need for nursing intervention?
- A. The client states he feels a continuous urge to void.
- B. The catheter drainage is light pink with occasional clots.
- C. The catheter is pulled taut and taped to the client's thigh.
- D. The client complains of painful bladder spasms.
Correct Answer: D
Rationale: Painful bladder spasms can indicate complications such as clot formation or obstruction, requiring immediate attention.
On inspection of the internal structure of the vagina, the nurse notes a rounded protrusion on the posterior wall of the vagina. How does the nurse document this finding?
- A. Rectocele
- B. Cystocele
- C. Bartholin cyst
- D. Nabothian cyst
Correct Answer: A
Rationale: The correct answer is A: Rectocele. A rectocele is a herniation of the anterior rectal wall into the posterior vaginal wall. The rounded protrusion on the posterior wall of the vagina indicates a rectocele. This finding is documented as a rectocele due to the specific anatomical location and nature of the protrusion.
Summary of other choices:
B: Cystocele - A cystocele is a herniation of the bladder into the anterior vaginal wall, not the posterior wall.
C: Bartholin cyst - Bartholin cyst is a fluid-filled swelling in the Bartholin gland near the vaginal opening, not on the posterior wall.
D: Nabothian cyst - Nabothian cysts occur on the cervix and are not related to protrusions on the posterior wall of the vagina.
