The patient asks Nurse Vera, when could you hear the fetal heart of my baby? Which of the following should be the BEST answer of Nurse Vera?

Correct Answer: C

Rationale: The correct answer is C: Fifth month. Nurse Vera should explain that the fetal heart can typically be heard using a Doppler ultrasound device around the fifth month of pregnancy. This is because the baby's heart is developed enough to produce audible sounds by this time. Choices A, B, and D are incorrect because in the ninth month, the baby is ready for delivery, in the third month the heart is still developing, and in the first month the heart is just beginning to form and is not yet audible.

Correct Answer: C

Rationale: The correct answer is C: Systematic sampling. Nurse Sandy is adopting systematic sampling by selecting every third patient with MI after a random start. This method ensures equal chance of selection for each patient and maintains randomness. In contrast, simple random sampling (A) entails each patient having an equal chance of being selected independently. Stratified sampling (B) divides patients into groups based on certain characteristics, which is not the case here. Cluster sampling (D) involves grouping patients and selecting entire groups, which is different from the individual selection in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Platelet count. Platelet count should be monitored closely during clopidogrel therapy because it works by inhibiting platelet aggregation, reducing the risk of clot formation. Monitoring platelet count helps assess the drug's effectiveness and prevent potential complications like bleeding or clotting events. Prothrombin time (A), activated partial thromboplastin time (B), and international normalized ratio (D) are tests that primarily assess the coagulation factors and are not directly affected by clopidogrel therapy, making them less relevant for monitoring this specific medication.

Correct Answer: B

Rationale: The correct answer is B: Prevents postpartum hemorrhage. Methylergonovine maleate is a uterotonic medication used to prevent and treat postpartum hemorrhage by causing strong uterine contractions, which help to control bleeding after delivery. It is not used to reduce lochia drainage (choice A), decrease uterine contractions (choice C), or maintain normal blood pressure (choice D). By understanding the pharmacological action of methylergonovine maleate in preventing postpartum hemorrhage, we can confidently select choice B as the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Ectopic pregnancy. In this scenario, the combination of missed periods, positive pregnancy test, and empty uterus on ultrasound with fluid in the cul-de-sac is highly suggestive of an ectopic pregnancy. Ectopic pregnancy occurs when the fertilized egg implants outside the uterus, commonly in the fallopian tube. The presence of fluid in the cul-de-sac indicates possible blood from a ruptured ectopic pregnancy, causing the severe lower abdominal pain. Ovarian cyst rupture (A) typically presents with less severe pain. Septic abortion (C) would present with signs of infection and products of conception in the uterus. Ovarian torsion (D) would present with acute onset of unilateral lower abdominal pain and a palpable adnexal mass, not fluid in the cul-de-sac.

Correct Answer: B

Rationale: The correct answer is B: 20-Gauge. The smaller the gauge number, the larger the diameter of the catheter. Blood transfusions typically require a larger catheter size to prevent hemolysis and ensure proper flow. A 20-Gauge catheter is larger than 22-Gauge, 18-Gauge, and 12-Gauge, making it suitable for administering blood. 22-Gauge is too small and can cause hemolysis, 18-Gauge is smaller than the recommended size for blood transfusions, and 12-Gauge is too large and can cause damage to the vein.

Correct Answer: C

Rationale: In a postpartum client who presents with severe abdominal pain, nausea, and vomiting, it is crucial to assess for signs of peritonitis or surgical abdomen. These signs may include rebound tenderness, guarding, rigidity, and fever. Peritonitis is a serious condition that may require immediate surgical intervention. Administering antiemetic medication, encouraging clear fluids, or providing a heating pad may not address the underlying cause of the symptoms and delay appropriate treatment. Assessing for signs of peritonitis or surgical abdomen is crucial for prompt identification and management of the client's condition.

Correct Answer: D

Rationale: The correct answer is D: Atropine. Atropine is a mydriatic agent that can exacerbate acute angle closure glaucoma by dilating the pupil and potentially worsening the condition. The nurse should discuss with the attending physician before administering it to avoid worsening the patient's condition. A: Isopto carpine eye drops are actually used in the treatment of acute angle closure glaucoma as they help in lowering intraocular pressure, so there is no need to discuss this with the physician. B: Mannitol is used as an osmotic diuretic to reduce intraocular pressure in acute angle closure glaucoma, and it does not directly affect the pupil, so it does not require discussion with the physician before administration. C: Corticosporin ophthalmic is a combination of an antibiotic and a corticosteroid used to treat eye infections and inflammation, but it does not have a direct effect on worsening acute angle closure glaucoma, so it does

Correct Answer: C

Rationale: The correct answer is C because independence for the elderly means they have the freedom to make choices and decisions about their own lives. This empowers them to live according to their preferences and values. Choice A is incorrect because it doesn't consider individual circumstances; choice B is important but doesn't capture the essence of independence; choice D is too broad and doesn't specifically address the concept of personal autonomy and agency for the elderly.
