Correct Answer: A

Rationale: A nightlight will help reorient the client to his or her surroundings in the evening and nighttime hours. It is best not to challenge the reality of a client experiencing Sundowner's Syndrome, and sedatives may make the effects of the syndrome worse. Every effort should be made to keep the client's room calm, quiet, and peaceful, so noise should be kept to a minimum. Reminding the client that what they are experiencing is not real may cause distress and confusion, while turning on the TV or radio may add unnecessary stimulation instead of promoting a soothing environment.

Correct Answer: A

Rationale: The best response for the LPN to provide to a pregnant client concerned about preventing Group B Strep is that it cannot be prevented, only treated. Group B Strep is a normal flora found in the vagina, rectum, and intestines of about 25% of women and is not a sexually transmitted disease. Testing for Group B Strep is done in each pregnancy, usually around 35-37 weeks. If a woman tests positive, antibiotics are administered during labor to reduce the risk of complications for both the mother and the baby. Choice A is the correct answer as Group B Strep cannot be prevented but only treated. Choice B is incorrect; condom use does not prevent Group B Strep. Choice C is not the best response as hand-washing is important for general hygiene but does not specifically prevent Group B Strep. Choice D is incorrect as there is no vaccine available to prevent Group B Strep.

Correct Answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

Correct Answer: B

Rationale: The correct location to palpate the dorsalis pedis pulse is lateral to and parallel with the extensor tendon of the big toe. Choices A, C, and D describe the locations for other pulses - popliteal, posterior tibial, and femoral artery respectively. The popliteal pulse is found behind the knee, the posterior tibial pulse is located in the groove between the malleolus and the Achilles tendon, and the femoral artery is situated below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines.

Correct Answer: D

Rationale: The correct answer is D: 'Rustling.' Vesicular breath sounds are described as rustling and resemble the sound of wind blowing through trees. Harsh, hollow, and tubular sounds are associated with bronchial (tracheal) breath sounds, not vesicular breath sounds. Harsh sounds are high-pitched, hollow sounds are reverberating, and tubular sounds are like blowing air into a tube. Therefore, options A, B, and C are incorrect descriptions of vesicular breath sounds and are more characteristic of bronchial breath sounds.
